What are leukocytes and how much should be in the blood (the norm in a healthy person). Why white blood cells are elevated: causes and treatment White blood cell count

Without immunity, human existence is impossible. A huge number of microbes live on the surface of our body, we daily encounter dozens of viruses and harmful factors (cold, stress, overheating, physical overexertion, etc.). If the body were not protected from all these influences, serious illness and death would not be long in coming. Leukocytes (white blood cells) are the most important component of this protection, which keeps a person alive.

To determine the number of these cells, it is enough to conduct a general blood test. This indicator can significantly change up or down with various diseases. Knowing the normal level of leukocytes, even an ordinary person can suspect the presence of a certain disease. However, it is important to remember that only a doctor is able to correctly diagnose and treat various pathologies.

What are leukocytes

This term denotes not one specific cell, but about a dozen different microscopic formations. Why are they named with the same name? Only because of their similar functions. Each of them ensures the proper functioning of the immune system, being activated when exposed to various harmful factors and the development of inflammation. For a better understanding, leukocytes can be divided into 4 large groups:

leukocytes under the electron microscope

Additionally, doctors secrete monocytes as a special component of the immune system. However, changes in their number are not very informative and are recorded extremely rarely.

Normally, a blood test for leukocytes should show a certain amount of each of these types of cells. An increase or decrease in their content, in most cases, indicates the presence of a disease or an incorrect diagnostic procedure.

Normal white blood cell counts

The number of white blood cells is determined by the state of the body, therefore, when evaluating a blood test, it is necessary to take into account the age and individual characteristics of each patient. Also, normal values ​​may vary slightly from laboratory to laboratory, depending on the apparatus used. Therefore, the laboratory assistants print the optimal values ​​for each indicator directly on the diagnostic results sheet.

In the absence of these data, the following table by age can be used:

Patient group	Total white blood cell count, WBC 10 9 /liter	Neutrophils, NEU %		Lymphocytes, LYM %	Eosinophils, EO %	Basophils, BA %
		Segment nuclear	wand nuclear
In newborns (the first 3 days of life)	9-30	47-70	3-14	15-35	1-6	0-1
The norm of leukocytes of a child up to a year	5,9-17,5	16-46	1-5	45-69
2-3 years	5,4-15,5	29-48		34-55	1-7
4-6 years old	4,9-15	32-54		31-50
7-10 years old	4,6-13,5	40-60		29-51	1-5
11-16	4,4-13	44-60		30-47
Adults (over 16 years old)	4-9	48-70		19-40
pregnant First trimester	4-9	40-79	1-6	18-44	0-5
Second trimester	up to 11
third trimester	Up to 15

The presence of deviations from normal values ​​up or down is a reason to consult a doctor to find out the cause. In most cases, changes in the blood are associated with the presence of a disease or a violation of the immune system.

Reasons for the increase in the number of cells

Exceeding the norm of leukocytes can be detected with improper preparation for analysis or against the background of an illness. In the first case, the number of white blood cells increases slightly - by no more than 2 * 10 9 cells / liter. In a healthy person, such changes are often observed in the following conditions:

• With a recent meal (within 3 hours before taking blood);
• After physical or emotional overload;
• Within 1-2 hours after water procedures with high / low temperature;
• A few days before menstruation.

In other cases, the deviation from the norm of leukocytes in men or women upwards is considered a pathological sign. This indicator does not allow to determine the affected organ, but it reliably indicates the presence of an inflammatory disease. Why is it so important? At the first examination of a patient, it can be quite difficult to distinguish between similar diseases, such as osteoarthritis and seropositive arthritis. A blood test can make it easier for the doctor to make a diagnosis.

The total number of all leukocytes can increase with the following pathologies:

Group of diseases	Examples	Why is the number of cells increasing?
Bacterial or fungal infections (rarely viral)	Skin diseases (pyoderma, erysipelas, furunculosis, etc.); Respiratory tract infections (pharyngitis, tonsillitis, bronchitis, pneumonia, etc.); Intestinal infections (salmonellosis, escherichiosis, typhoid infection, etc.); Urinary tract infections (pyelonephritis, cystitis, urethritis); Neuroinfections (meningitis, encephalitis).	White blood cells are attracted to the focus of the disease and try to cope with a harmful microorganism. This requires a large number of cells, so their level in the blood can rise significantly.
Autoimmune diseases	Lupus erythematosus; scleroderma; Rheumatoid arthritis; Rhematic fever (old name - rheumatism).	With these pathologies, the immune system "mistakes" and lymphocytes begin to attack their own tissues. With exacerbations, their number in the clinical blood test often increases.
Damage to internal organs	Biliary tract (calculous cholecystitis, cholangitis); Urolithiasis disease; Heart attack (heart, lung, kidney and other organs); Stroke.	The human body responds to almost any damage with inflammation. This process attracts leukocytes from the "depot".
Injuries	fractures; Any wounds (especially gunshot and contaminated); Burns/acute frostbite.
blood tumors	Leukemia; Lymphogranulomatosis;	Blood is the same tissue as muscles, adipose tissue or connective tissue fibers. With uncontrolled growth, a multiple increase in its components (white cells) occurs.

An excess of white blood cells in the blood in women or men may be an indirect sign of any of these conditions. To narrow the "circle of search", the doctor may recommend determining the leukocyte formula. This is a special blood test that allows you to evaluate the number of various white blood cells (eosinophils, neutrophils, etc.). What is evidenced by the excess number of each type of cell, you will learn below.

Eosinophils and basophils

These are the main "indicators" of allergies. An increase in their number in the presence of typical symptoms (rash, runny nose, swelling of the skin) suggests this diagnosis with a high degree of probability. It is possible to reliably confirm it and determine the substance that caused the exacerbation of the disease with the help of allergy tests.

How are allergy tests performed? There are several variants of this analysis, but at present, the scarifying method is considered the most practical. Its principle is as follows - shallow scratches are applied to the skin and the most common allergens (essence of dust, pollen, animal dander, etc.) drip into these places. If signs of inflammation (significant redness, swelling) are found, the test is considered positive.

Neutrophils

In most patients, the level of neutrophils increases due to the presence of a bacterial infection. It is this change in the blood that makes it possible to distinguish them from viral diseases and to choose the right treatment tactics. A significant excess of the norm often indicates the presence of a serious illness and may be an indication for hospitalization of the patient in a therapeutic hospital.

Other causes of a large number of neutrophils can be the following pathologies:

• Any damage to organs and tissues (heart attacks, cholecystitis, strokes, etc.);
• Serious injuries (fractures, burns, etc.);
• Leukemia;
• Poisoning with poisons (lead, mercury, animal poisons).

Lymphocytes

These cells are released into the blood from the depot during the development of viral diseases. As a rule, lymphocytes react quite slowly - their number begins to increase after a few days, and the first antibodies appear no earlier than after 1.5-2 weeks. However, this component of immunity is practically the only defense against viruses. Also, the level of lymphocytes can increase with exacerbation of autoimmune pathologies, the presence of fungal infections and leukemia.

Causes of a decrease in leukocytes

Improper functioning of the immune system, first of all, is reflected in the number of white cells. A decrease in their content in the blood indicates a weakened defense of the body and the presence of a disease. Most often, the following pathologies lead to low levels of leukocytes:

Group of diseases	Action on the number of cells
Viral infections (influenza, RS virus, noroviruses, etc.)	Some viruses are able to suppress the natural immunity of a person, which is manifested by a deficiency of blood cells.
HIV	This virus has a special effect on human blood, so it must be isolated in a separate group. HIV is a chronic disease that selectively affects human leukocytes and leads to a decrease in their number. The longer the pathology proceeds without adequate therapy, the worse the protection of the body. How relevant is this problem? According to the statistics of Roszdravnadzor, every 50th Russian suffers from this disease. Unofficial statistics (and probably more truthful) give other figures - every 10th person in the Russian Federation is ill with HIV. Therefore, if a lack of white cells is detected without an obvious reason, the patient should necessarily take a rapid test for this virus.
Severe conditions of the patient (with sepsis, severe pneumonia, meningitis, etc.)	In these conditions, all body functions, including protective ones, suffer. Due to the action of a strong damaging factor, the immune system is not able to adequately cope with it and, as a result, is gradually depleted. Downward deviation of blood counts is always an unfavorable sign.
Bone marrow damage (common osteomyelitis, myelofibrosis and other pathologies)	Almost all blood cells are produced in the bone marrow. Therefore, if this process is disturbed by any harmful factor, the number of blood cells decreases.
Violation of the production of white blood cells (after taking cytostatics, chemotherapy, antiepileptic drugs, with radiation sickness)

Only a qualified doctor can correctly identify and cure the cause of a decrease in the rate of leukocytes in the blood in children and adults. Almost always, this deviation indicates a disturbed work of the immune system. Therefore, when it is detected, it is recommended to consult a specialist, and not to engage in therapy on your own.

Preparing for a blood test

In order to reliably determine how many leukocytes are in your blood, you must follow the following recommendations:

• Take the test no earlier than 3 hours after eating;
• Within 3 hours, exclude the use of caffeine- and sugar-containing drinks, alcohol and tobacco;
• Limit physical activity 30-40 minutes before donating blood;
• Do not take hot baths, contrast showers and other water procedures with an uncomfortable temperature for the body before going to the hospital.

If these rules are not followed, the level of white cells may slightly exceed the norm or be at its upper limit. This change can lead to a diagnostic error and an incorrect assessment of the state of health.

FAQ

Question:
Why does the number of white bodies decrease with age?

All human tissues are subject to aging processes, which inevitably affects their functions. The weakening of the body's defenses is one of the manifestations of this process.

Question:
What is the norm of leukocytes in women? Do they have any special features?

The number of these cells does not depend on gender, but may slightly increase before and during menstruation.

Question:
Does this indicator change with tumors of the internal organs?

In most cases, it remains within the normal range.

Question:
If the level of cells decreases after taking medications, should they be canceled?

The decision to stop taking medication is decided individually, depending on the degree of reduction of white blood cells and the patient's condition. As a rule, with a slight decrease in the WBC, it is recommended to continue therapy. In any case, this issue should be discussed only with the attending physician.

Experienced physicians can say about the health of the patient precisely by the state of leukocytes. A person cannot identify this indicator on his own. In order to correctly read the analysis, it is necessary to understand what leukocytes in the blood are responsible for, to know the permissible fluctuations of this indicator. You should also know what is worse: going beyond the lower or upper bound.

What are leukocytes

Human blood is a connective mobile tissue, subdivided into the main liquid medium, which is called plasma, as well as into dense elements, which include:

• platelets;
• erythrocytes;
• leukocytes.

What are white blood cells responsible for? In general, leukocytes are white blood cells that make up the middle layer of a gray tint in the settled part. If we consider the blood in the laboratory with a multiple increase, then the leukocytes look like small spheres that have an irregular shape, with a rough surface. The white hue of leukocytes is due to the absence of color, which cannot be said about erythrocytes.

Leukocytes are synthesized, like other blood cells, by the bone marrow. The total amount of all formed elements in human blood is no more than 50%. The number of leukocytes in this case should be an order of magnitude less than that of erythrocytes and platelets.

What are leukocytes in the blood? Their letter designation in the blood test is WBC - White Blood Cells.

What are white blood cells responsible for?

These bodies play a huge role in the protective functions of the human body, as they participate in immune reactions, synthesize special T-cells - lymphocytes. Speaking about what lymphocytes are responsible for in the blood, it should be noted that they recognize infectious agents that enter the human body, and then destroy them. If the process of release of lymphocytes by leukocytes was carried out correctly, then immunity is stimulated for the production of special antibodies, which is very important in the presence of infectious diseases, as well as any inflammatory processes. If someone does not know what white blood cells are responsible for in the blood, then their main role is to protect the body.

How long can they live

The lifespan of each form of leukocytes is different. For example, granulocytes begin to die after 10 days, lymphocytes, which are especially important for the immune system, function in the human body for several years, after which they are replaced by new ones.

Monocytes have the shortest lifespan, which is 1-2 hours. This is due to the fact that they face the simplest task.

All forms of leukocytes are destroyed in the spleen or in the area of ​​the inflammatory process.

Varieties of leukocytes

The main indicator that determines the state of human health is not only the total number of leukocytes, but also the percentage of their types, according to which experts put forward various hypotheses about the causes of the deviation from the norm. The main types of white blood cells include:

1. Neutrophils. These elements are among the granular leukocytes. If their level falls, this will lead to the loss of the human body's ability to defend itself against various direct and bacterial infections. Neutrophils that died at the site of inflammation are pus.
2. Lymphocytes. Lymphocytes are the main defenders of the human body in the presence of viral infections. It is they who destroy and recognize alien agents.
3. Monocytes. The main role of monocytes is that they purify the focus of inflammation from dead various foreign particles.
4. are considered to be accessory cells that mobilize other granular leukocytes to the main site of the inflammatory process.
5. Eosinophils. These granulocytes perform an anti-allergic function in the human body.

The norm of leukocytes

The number of these white blood cells is not considered fixed. Even throughout the day, the leukocyte count will fluctuate, as it is tightly interconnected with various external factors. What determines the number of leukocytes in the blood? The physiological increase in this indicator is affected by:

1. Times of Day. For example, before going to bed, the level of white blood cells increases in the blood.
2. Too much protein in the diet.
3. Weather conditions, which should also include the immune response to sudden changes in air temperature.
4. Pregnancy period.
5. Stressful state.
6. menses in women.

You should also pay attention to the fact that the constant concentration of these bodies in adults is always lower than other formed elements in the blood. For example, if we compare the number of leukocytes with erythrocytes, then the former are a thousand times less.

Doctors also note that in newborns during a blood test, a rather high level of white cells is observed, 3 times more than, for example, in an adult. However, over time, their rate gradually decreases, the difference in women and men is observed only after the 21st year of life.

Elevated white blood cells

Elevated leukocytes in the blood - what does it mean? Before answering this question, it is worth paying attention to the fact that any fluctuations in the rate of white blood cells in the blood have their own names in the field of medicine. For example, an increase in the level of white blood cells is called leukocytosis. By the nature of its prerequisites, leukocytosis can be physiological or pathological. Physiological leukocytosis in women appears during pregnancy, menstruation, childbirth. In patients of both sexes and all ages, leukocytosis appears due to stress, physical exertion, and the use of certain foods.

If we talk about pathological leukocytosis, then it should be considered in more detail, since it can indicate the presence of dangerous diseases.

Possible causes of leukocytosis

What does it mean - elevated leukocytes in the blood? Answering this question, one should pay attention to the fact that the fair sex has more reasons to face this disease than men. One of the natural prerequisites for this phenomenon is pregnancy, in which deviations of this indicator from the norm up to 15 * 10 ^ 9 U / l are allowed. However, this is not considered a sign of the presence of any disease. The same deviations are allowed if the blood test was taken after eating or exercising. If the increase in leukocytes does not apply to these cases, then the reasons may lie in the following:

• the presence of viral diseases;
• the presence of bacterial infections;
• inflammatory processes of any etiology;
• anemia;
• kidney failure;
• internal bleeding;
• allergic reaction;
• injury to the skin, such as burns or wounds.

Separately, a strong deviation of this indicator should also be mentioned when the number of leukocytes is more than 100,000 * 10 ^ 9 U / l. It is with oncology that leukocytes in the blood increase to such indicators. Officially, this disease is called leukemia or leukemia. Mostly this problem is diagnosed among children. If the number of leukocytes increased only to 10000 * 10 ^ 9 U / l, then this may happen due to the presence of an inflammatory process in the human body, the nature of which must be investigated.

What to do

If leukocytes in the blood are increased, what is done in this case? This will require a comprehensive examination, which includes:

• smear of peripheral blood;
• performing a biopsy;
• delivery of a detailed analysis for an increase in basophils.

The underlying cause of the increase in leukocytes should also be addressed, so treatments will be determined based on the underlying cause of the leukocytosis. In the presence of acute infections, antibiotics may be used, and in case of blood pathologies, chemotherapy will be required. Additionally, there are also:

• anti-inflammatory drugs;
• antacids to reduce the amount of acid in the urine.

Decreased level of leukocytes

Medical data suggests that the deviation from the norm mainly goes up, but a decrease in this indicator is also possible. This phenomenon is called leukopenia. As for the physiological prerequisites for this disease, they are few. Statistics show that only 12% of Europeans suffer from a congenital form of this pathology. The function of immune cells does not change, so these patients do not need therapy. As for the pathological decrease in the number of leukocytes, the prerequisites for this are very serious.

Causes of leukopenia

If the function of the bone marrow is impaired, then it can no longer produce leukocytes in the required volume, and their indicator drops by two units or more, while remaining at a minimum level for a long time. From analysis to analysis, this indicator begins to decline. In adults, this happens for the following reasons:

• the presence of malignant diseases of the lymphoid tissue;
• chronic diseases that are infectious in nature;
• low-quality tumors;
• metastases in the bone marrow;
• severe blood loss;
• hepatitis;
• intoxication.

A decrease in the level of white blood cells can also be observed due to the use of nonsteroidal drugs and antibiotics, as well as in the presence of sepsis. Low white blood cells in the blood of a child are observed due to a pathological process, which is predominantly congenital. In this case, specialists place special emphasis on:

• hypoplasia or aplasia of the bone marrow;
• vitamin B12 deficiency.

How to increase white blood cells

If the number of leukocytes has decreased due to weakened immunity, then to increase this indicator, you need to adjust your diet. What foods increase white blood cells? These should include:

• beetroot juice and pomegranate;
• fresh fruits, especially red ones;
• oatmeal and buckwheat.

You should also pay attention to the fact that offal and meat should be removed from the diet.

Additionally, it is also necessary to use drug therapy in order to increase leukocytes, which is prescribed only by a doctor. Very good results can be achieved after the use of the following drugs:

1. A leucogen that is completely non-toxic and non-accumulative. The course of admission should be 1-3 weeks.
2. Leukomax, which is administered subcutaneously, is recommended mainly for neutropenia. It is used strictly under the supervision of a specialist.

Folk remedies

If leukopenia is not caused by congenital diseases, then the following folk remedies can be used:

1. Mix two parts pollen with one part natural honey. Let it brew for 3 days, after which the finished product should be taken one teaspoon in the morning with warm water.
2. For a month, use a decoction based on oat grains. To prepare it, you need three tablespoons of purified raw materials, pour 300 ml of water, let it brew for 10 minutes, filter. At a time, 50 ml of the finished product is drunk in the morning and evening.

In conclusion, it is worth noting that the main function of leukocytes in human blood is to protect the body from various harmful viruses and bacteria. However, the deviation from the norm of this indicator is not always associated with the presence of some kind of disease.

For any ailment, one of the first studies that a doctor prescribes in order to establish the cause of the disease is the UAC. The indicators of the level of white blood cells displayed there will immediately tell the specialist where to look for the cause of the disease. To navigate what this analysis may indicate, find out in more detail what the rate of leukocytes in the blood of women should be and what could be the reasons for changes in the leukocyte formula.

Deciphering the leukocyte blood formula

Leukocytes are called several types of cells that make up the blood, which, unlike red blood cells that transport oxygen throughout the body, perform an immune function - they protect against infections. In the results of the analysis, they can be abbreviated as WBC (from the English white blood cells, which translates as “white blood cells”). The percentage ratio between them, calculated during the study, is called a leukogram, or leukocyte formula.

During the analysis, all types of this type of blood cells are counted:

• Granulocytes, which are also called granular cells, are the most numerous group, their number is up to 80% of all white blood cells. These include:
  • neutrophils (stab and segmented granulocytes);
  • eosinophils;
  • basophils.
• Agranulocytes - up to 28% of the total, to perform a protective function, they can leave the bloodstream and penetrate into the connective tissue. These include:
  • lymphocytes;
  • monocytes.

The norm of the number of leukocytes in the blood in women

Indicators (norms) differ for people of different ages and gender, and also depend on the physical condition of the person. For example, their level rises after physical exertion or in the evening, when daytime fatigue affects. The level of WBC in women increases during pregnancy, after childbirth, during menstruation. How many white blood cells should be in the blood of an adult woman? Look at the allowable numbers in the table below, which indicates the designation of leukocytes in a blood test and their normal limits.

Increased white blood cells

An increased content of the analysis parameter is said when the amount exceeded 9 * 109 / l. This change in blood composition is called leukocytosis. A very large excess of the norm (50-80 * 109 / l) can even indicate leukemia - blood cancer. What exactly such a high concentration of white blood cells indicates, only a specialist can and should establish, because a variety of factors can cause this condition.

Causes

In some conditions of a woman, an increase in the WBC indicator is a variant of the norm: for example, the numbers can be increased after childbirth, or if a woman feels very hungry, and even immediately after eating. Leukocytosis during pregnancy is not considered a disease, which, in addition to a natural increase in such a parameter during this period, can be caused in a pregnant woman even by ordinary thrush (candidiasis).

If the factors that could distort the results of the tests are excluded, the doctor determines which root cause activated the growth, for example:

• bacterial or viral infections;
• traumatic injuries of the body, suppuration, burns;
• allergic reaction;
• food poisoning that caused vomiting, diarrhea;
• kidney failure;
• acute appendicitis, etc.

How to downgrade

It is possible to normalize the number of leukocytes in the blood of women by influencing the causes that violated it. So, if such an indicator appeared due to physiological reasons - overwork, stress - you need to normalize the schedule of work and rest, eat right, prevent overheating of the body and not overcool. If a disease has led to an increase in the WBC number in the formula, then the tests are normalized due to the treatment of the disease. Appropriate therapeutic measures should be selected only by a general practitioner or hematologist based on his diagnosis.

Leukocytes in the blood are low

A decrease in the level of white blood cells indicates leukopenia. This is a dangerous condition for health, because it indicates a significant decrease in the body's defenses. If the indicator of this blood component in a woman is less than 3.7 * 109 / l, this is already a signal of the presence of a disease. In cases where the low level of leukocytes approached 1.7 * 109 / l, they speak of the development of a serious blood disease. With a low WBC, you should immediately go to an appointment with a competent doctor.

Reasons for the low level

Proper diagnosis in leukopenia is very important, because such changes can be caused by serious disturbances in the very process of producing white blood cells. This happens when:

• violations of the normal process of formation of a component by the bone marrow due to trauma, oncological disease of this organ;
• insufficient amount of trace elements and organic substances - vitamins of group B, copper, iron;
• if a person is sick with radiation sickness, AIDS, an autoimmune disease;
• with an inborn predisposition.

The second group of reasons that causes a decrease in the numbers in the analyzes is a decrease in the number due to death after performing protection functions. This happens when:

• the development of an infectious disease;
• disruption of the spleen and liver;
• increased cell destruction as a result of prolonged use of drugs or the action of strong drugs, such as chemotherapy;
• hormonal disorders.

Raise

Identified leukopenia necessarily requires qualified treatment in order to restore the body's ability to self-defense. Together with the impact on the disease that caused such a deviation from the norm, it is necessary to use drugs that stimulate the production of white blood cells, and pay attention to the diet, use the necessary vitamin complexes.

Discuss

leukocytes in the bloodno one even thinks about them. And why should a person be interested in a topic that does not bother him at all. But what are these elements? Although leukocytes are called the white cells of our blood, they are colorless because they lack components that can determine color.

The common name of leukocytes does not indicate their homogeneity. Populations are represented in the blood different types of cells belonging to two categories: granular elements, better known as granulocytes, as well as agranulocytes.

Leukocytes, their types and functions

The work of leukocytes in the blood human based on the absorption of pathogenic microorganisms, which ensures their neutralization. Sometimes this action leads to the fact that the leukocyte itself dies like a hero. The functional load of these blood Taurus also captures the complete cleansing of the body, in which particles of unabsorbed bacteria and dead brethren are removed. Leukocytes have their own memory, they produce antibodies, which subsequently allows them to develop immunity to a specific disease.General blood analysisreveals several types of cells in the norm, and each performs a specific task:

It is difficult to overestimate the functionality of these elements in relation to the protection of human health. They are obliged to prevent the action of adverse factors, fighting at the immune level:

• granulocytes instantly enter into a fight with "enemy" substances, preventing their settlement;
• lymphocytes help to resist insidious enemies, providing the formation of antibodies;
• macrophages clear the "battlefield", removing toxic substances from the body.

Reveal white blood cell count, which seen in patients, it turns out if you donate blood for a general analysis. And it is also extended. Ordinary analysis will register only the generalwhite blood cell count, but the extended one is able to concretize leukocyte status by type and number of cells.

The really incredibly useful role of leukocytes in protecting human health will be discussed in more detail in the video below. The topic is disclosed in an accessible human language, so even a person completely far from medicine will immediately understand everything without additional searches for information on specialized Internet resources:

Norm by age

Normal level the number of leukocytes in the blooddiffers in people - it all depends not only on their age, but also on the diet, time of day. This indicator practically does not depend on gender alone, although there are fluctuations here as well. Leukocyte percentage compositionin an adult on age in the tablelooks after analysis laboratories as follows:

In deciphering theseindicators shouldindicate the total content of cells of the immune system in the blood. For diagnosis, it is important not only to change from the norm for any group, but also to grow with leukocytosis or reduced valuesthe total number of leukocytes. When the question concerns the norm, the doctor will certainly take into account the age of the person, since it affectsphysiological features body:

Attention! Elderly patients usually have reduced immunity. Therefore, diseases for leukocytosis are practically not observed when reaching the age of 60. If this happens, you need to consult a doctor.

Norm for women

Results table deviationsfemale analysis are characteristic of certain periods of her life, when leukopenia or leukocytosis do not indicate the presence of pathology. This condition occurs during pregnancy.

A summary table of leukocyte indicators inherent in women at different ages looks like this:

Such figures indicate that one should not panic if deviations are found, since each such situation is considered individually.

Values ​​during pregnancy

The norm of white blood cells in pregnancy timeincreases significantly, since the body is obliged to protect both itself and the growing fetus. In the first trimester these blood cells remain normal, since female immunity must remain at a low level so that the fetus is not perceivedimmune responseas a foreign element. But from the second trimester, signs are already noticeableincrease in, because the female body undergoes significant hormonal changes. Causes excess of normal values ​​in pregnant women, for which the doctor will turn attention, such:

• latent infections;
• a number of diseases genitourinary system;
• frequent bleeding;
• trauma;
• oncology;
• allergy.

The provocateurs of a decrease in values ​​in pregnant women are:

• flu;
• measles and rubella;
• work disruptionhormonal system;
• hepatic and renalpathological processes;
• problems in the gastrointestinal tract.

Therapy of pathologies is first discussed with the gynecologist, it is certainly gentle, since the main task is not to harm the fetus. Similar to the actions in leukocytosis, leukopenia also requires careful examination.human healthto identify the true root cause of the violations.

Timely cured problems guarantee a favorable outcome of pregnancy for a woman at the same time as a child. It could be considered that a violation of the values ​​​​of the norm of leukocytes is a frequent occurrence, observed in almost every pregnant woman. When the reason for such reactions easily removable, this phenomenon does not affect thelevels of immunityfuture baby and childbirth. The most dangerous disease is rubella, since it is it that has the most negative effect on the favorable development of the fetus.

There are frequent situations when the outcome of such a disease is a forced termination of pregnancy. It occurs spontaneously or it is organized, guided by the testimony. It is rubella that can provoke all kinds of deformities and malformations of the unborn baby,which testifyabout serious problems, sometimes completely incompatible with the future life of the child.

A similar requirement applies to the timely diagnostic examination of a pregnant woman. You can not skip scheduled consultations with your gynecologist, ignore the diagnostic procedures recommended by him. The sooner the diagnosis reveals violations inbone marrow and blood, which provoked a change in the leukocyte count, the easier the upcoming treatment will be, it will be gentle, and reduce the dangers to the health of the fetus. The main thing is not to despair prematurely, because a positive attitude will ensure a confident victory over diseases.

Reasons for the increase

If translated into normal human language, then leukocytosis is the presence in the body of a certain inflammatory process,whose treatmentwill certainly restore normal levels of leukocytes anderythrocytes in the blood. Not only pathological, but also physiological factors are capable of provoking an increase in blood cells. That is why doctors distinguish between physiological leukocytosis and its pathological counterpart, which havesome differences one from the other.

Physiological

• exhausting physical work;
• eating before the test (food can significantly “spoil” the results, since after a meal the number of leukocytes often rises sharply, reaching 12 * 109 units / l);
• food leukocytosis develops with the predominance of meat products in the daily diet, since leukocytes are capable of think that certain components of such food are foreign antibodies and the immune response to them will be appropriate;
• value growth leukocytes after childbirth;
• taking contrast baths;
• vaccination.

Important! Also, their value increases slightly in the days before menstruation.

Reasons for the decline

If there is a lack of leukocytes, this is evidence that they have decreased to a value characterizing the development of leukopenia. This condition has nothing to do with blood type , the gender of the person. There are such reasons that contribute to a decrease in the leukocyte index:

• damage to cells belonging to the bone marrow by all kinds of chemicals, including medications;
• hypoplasia or aplasia of bone marrow cells;
• deficiency of certain trace elements or certain vitamins (folic acid, iron, copper, vitamins B1 and B12);
• radiation sickness provoked by radioactive exposure;
• myelofibrosis or hypersplenism;
• myelodysplastic syndromes and plasmacytoma;
• metastases of neoplasms into the bone marrow;
• typhus;
• pernicious anemia;
• sepsis;
• anaphylactic shock;
• herpes virus, related to type 6 or 7;
• taking medications (sulfonamides, some antibiotics, NSAIDs, thyreostatics, cytostatics, antispasmodic or antiepileptic drugs);
• collagenoses.

Even with low white blood cells, the doctor must exclude the possibility of thyroid pathologies. When the value of white blood cells is found to be low in a child, such a problem can be provoked by influenza, typhoid fever, malaria, measles, rubella, brucellosis, or viral hepatitis. Therefore, leukopenia is always a serious pathology that requires immediate identification of the causes of the problem and their elimination.

When can a leukocyte test be ordered?

Direct indication that the doctor will direct the woman to performblood test for leukocytes- suspicion of the presence in her body of an inflammatory process that is in a "sleeping" state, or an infectious pathology. The most dangerous reason is a malignant tumor that develops in the bone marrow. It is she who is able to "force" leukocytes to dramatically increase their presence. Regularly monitoring the value of their number is required when performing radiation therapy. This will allow assessing the degree of effectiveness of organized treatment.

In general, it is advisable to visit a laboratory at any medical institution to donate blood for a general analysis.

How to prepare and pass the analysis correctly

In order to obtain the most reliable results when performing a blood test,white blood cell count, you will need to follow certain guidelines. This condition is explained by the fact that various factors can distort the real results.

Because of this, be guided by the advice of a doctor before visiting the laboratory, regardless of the option of taking blood - from a finger or a vein:

1. It is strictly forbidden to have breakfast - the most that you can allow before leaving the house is just a glass of plain water. There is also no reliable evidence that a cup of sweet tea can distort the results of the analysis.
2. Even a day before the study, it is necessary to stop intensive training, when a person is accustomed to devote a sufficiently long time to them daily.
3. Try to avoid strong emotional shocks as much as possible for at least a couple of hours before visiting the clinical laboratory.
4. It is not allowed to attend diagnostic procedures such as X-ray, ultrasound, CT or MRI a day before a blood test.

The most reliable values ​​are provided by a blood test taken from a vein. Such a paradox is explained by the probable additional release of leukocytes in response to strong squeezing of the finger, which occurs at the time of selection of the biomaterial from it.

Conclusion

When progressive leukocytosis is detected in a person, it is necessary to remember that this problem does not belong to the category of diseases. This is only a signal of the presence of a pathological process. As soon as it can be stopped and cured, the tests will return to normal on their own. Therefore, there is no need to personally interpret the result of a visit to the laboratory - visit an experienced specialist who will certainly prescribe a comprehensive examination first, and then make an accurate diagnosis and recommend adequate treatment for the pathology.

If the results of the analysis revealed few leukocytes, it is necessary to undergo a second study. When it confirms the deviations, the doctor prescribes a comprehensive examination. You will need to consult a hematologist in order to exclude the risk of blood diseases due to genetic abnormalities.

Leukocytes and their significance in analyzes: an increase and decrease in the number of leukocytes in a general urine test and in a blood test, as well as in a vaginal smear
Leukocytes or white blood cells are cells of the immune system that protect the human body from infections and viruses. An increase in the number of these blood cells in the blood in most cases is a signal that an infection has settled in the human body. A decrease in the level of leukocytes in the blood is almost always observed when the body's immune defenses are weakened. An increase in the number of white blood cells in the urine, as well as in a vaginal smear, indicates the development of inflammatory pathologies of the genitals, kidneys or bladder.

Leukocytes - what is it?

Leukocytes are called blood cells that do not have color, which can be very diverse in size and shape. Their size can vary from six to twenty microns, but their shape can be either irregular or round. In fact, a rather important function is assigned to white blood cells. They are the main barrier, which is an obstacle to the penetration of certain infections into the body. The composition of these cells includes special enzymes that tend to digest various microscopic organisms. In addition, it is these cells that help not only bind, but also break down foreign protein components, as well as decay products that are formed in the human body as a result of their vital activity. Plus, some types of leukocytes tend to produce antibodies, namely protein particles, which in turn destroy all microorganisms that have appeared on the mucous membranes, in the blood, or in tissues or organs. White blood cells form in the red bone marrow.

To date, experts distinguish two main types of these immune cells - these are granulocytes and agranulocytes. As for granulocytes, in these cells the cytoplasm is endowed with granularity. There are three forms of granulocytes: neutrophils, which in turn are divided into segmented and stab based on the appearance of their core, as well as eosinophils and basophils. If we talk about agranulocytes, then in their cells the cytoplasm is not endowed with granules. Agranulocytes can also be of two forms - these are monocytes and lymphocytes. Immediately, we note that all forms of white blood cells are endowed with amazing properties.

The rate of leukocytes in the blood

If a person is completely healthy, the number of white blood cells in his blood should be equal to 4.0-9.0 x 109/l.

The level of white blood cells in the blood of a child is determined by his age:

• First day - from 8.5 to 24.5 x 109/l
• In the first month - from 6.5 to 13.5 x 109/l
• At six months - from 5.5 to 12.5 x 109/l
• In year - from 6.0 to 12.0 x 109/l
• Up to six years from 5.0 to 12.0 x 109/l
• Until the age of twelve from 4.5 to 10.0 x 109/l
• For children aged thirteen to fifteen, from 4.3 to 9.5 x 109/l.

The number of leukocytes in the blood of a pregnant woman

During pregnancy, the number of white blood cells in the blood of the expectant mother may increase. up to 15.0 x 109/l. This is explained by the fact that during pregnancy a huge amount of these cells of the immune system is concentrated in the submucosa of the uterus. This happens because in this way the female body manages to protect the fetus from certain infections. In addition, a large accumulation of these cells in this area improves the contractile performance of the uterus.

Leukogram, or as it is also called leukocyte formula, is the ratio in the blood of certain forms of blood cells, which is expressed as a percentage.

These or other forms of white blood cells take part in a variety of protective reactions of the human body. As a result, thanks to the results of the analysis of the leukocyte formula, information can be obtained regarding the nature of the existing pathology. This information will help the doctor make an accurate diagnosis in the first place. An increase in the number of the youngest, as well as stab neutrophils, is considered to be a signal of blood rejuvenation. In such cases, experts talk about a shift in the leukocyte formula to the left. This kind of shift is especially often observed in inflammatory and infectious pathologies. Sometimes it is also observed leukemia accompanied by excessive production of leukocytes.

An increase in the number of leukocytes in the blood

A condition in which there is an increase in the number of leukocytes in the blood by more than 9.0 x 109/l, are called leukocytosis. We immediately draw the attention of readers to the fact that this condition can be both physiological and pathological. Physiological leukocytosis is a condition in which a person has an increase in the level of white blood cells in the blood against the background of normal life situations. Leukocytosis is called pathological when it indicates the presence of a particular disease.

A physiological increase in the level of leukocytes in the blood is possible under the following circumstances:

• two to three hours after eating digestive leukocytosis;
• as a result of excessive physical exertion;
• after cold or hot baths;
• due to mental or emotional overstrain;
• before the menstrual cycle or in the second half of pregnancy.

Since all of the above factors can provoke a jump in the level of white blood cells, it is recommended to take a complete blood count in the morning on an empty stomach. It is very important that before taking the test, the person does not take a bath, is not nervous, and does not perform hard physical work.

Among the most common causes of a pathological increase in the level of leukocytes in the blood can be considered:
Various infectious pathologies, namely:

• otitis media is an inflammatory process of the middle ear, which is especially common in childhood. This inflammatory disease is accompanied by pain, as well as noise in the ear. In addition, the patient may complain of fever, hearing loss, and discharge of pus from the ear.
• meningitis - inflammation of the membranes of the spinal cord or brain, in which nausea, vomiting, and also a very severe migraine are noted. In the presence of this pathology, the patient, as a rule, lies with his head thrown back, as well as with his legs bent to his chest.
• bronchitis, pneumonia, accompanied by pain when breathing, fever and a wet cough with sputum.
• erysipelas makes itself felt with fever, migraine and general malaise, after which inflammation of the skin occurs, in which the patient has blisters, swelling and redness. In most cases, this pathology is observed in the lower extremities.

Inflammatory processes and suppuration of various locations:

• pleura ( empyema, pleurisy), there are pain in the chest area when breathing,
• abdominal cavity (appendicitis, peritonitis, pancreatitis) - nausea, pain in the abdomen, fever,
• subcutaneous tissue ( abscess, felon, phlegmon) the development of pain in a particular area of ​​the skin, an increase in local temperature, the development of redness in a certain area, a sharp pain when pressed.

In principle, all inflammatory processes cause an increase in the level of white blood cells in the blood. If an increased amount of these cells was noted in a person’s blood, he should be sent for an additional examination, which will make it possible to establish the true cause of the development of a particular pathology.

Not so often, an increase in the level of leukocytes in the blood of adults and children is observed with the following diseases:

• Leukemia are a group of tumor pathologies in the presence of which the human bone marrow begins to produce an excessive number of abnormal white blood cells. Obvious signs of these diseases are: dizziness, hemorrhages, general weakness, enlarged lymph nodes, liver and spleen, bleeding of mucous membranes. It is possible to establish these pathologies only through examination of the bone marrow;
• diabetic coma;
• Condition after severe blood loss;
• Extensive burns;
• Chronic renal failure;
• Infarcts of the spleen, heart, kidneys, lungs.

Decrease in the level of leukocytes in the blood

A condition in which a decrease in the number of white blood cells in the blood is below 4.0 x 109/l, are called leukopenia. In most cases, a decrease in the number of white blood cells is considered to be a signal of inhibition of the formation of these cells in the bone marrow. In some cases, this condition develops as a result of excessive destruction of white blood cells. It also happens that these cells of the immune system simply remain in the depot organs for a sufficiently long period of time. As a result, the distribution process is disrupted. Most often, this condition occurs during collapse or shock.

In most cases, leukopenia develops against the background of conditions such as:

• radiation effect ( radiation sickness, accompanied by damage to the bone marrow, as a result of which there is a decrease in the formation of all blood cells);
• the use of certain pharmaceuticals: anti-inflammatory drugs ( analgin, butadione, reopyrin, pyrabutol); medications that depress the thyroid gland potassium perchlorate, mercazolil, propycil); antibacterial drugs ( chloramphenicol, sulfonamides, synthomycin); medicines used for the treatment of oncological pathologies, namely cytostatics ( vincristine, methotrexate, cyclophosphamide and so on);
• aplastic or hypoplastic pathologies, accompanied by a decrease in the formation of both leukocytes and other blood cells, and for unknown reasons;
• some forms of pathologies in which there is an increase in the efficiency of the spleen, which in turn leads to excessive destruction of leukocytes: syphilis, liver cirrhosis, tuberculosis, lymphogranulomatosis;
• certain pathologies of an infectious nature: typhoid fever, viral hepatitis, malaria, measles, influenza, brucellosis, rubella;
• systemic lupus erythematosus;
• anemia, in which there is a lack of a vitamin AT 12;
• oncological pathologies accompanied by metastases to the brain;
• the initial stages of the formation of leukemia.

A critical drop in the level of white blood cells is called agranulocytosis. In most cases, this condition is observed against the background of the use of certain drugs. In fact, agranulocytosis is considered to be an extremely dangerous condition, and all because without white blood cells the human body is not able to fight even the most insignificant infectious pathologies.

Leukocytes in urine

To detect white blood cells in the urine, urine samples must be examined under a microscope. The level of these cells in the urine is measured by the number of leukocytes that can be detected in one field of view under a microscope. The normal number of white blood cells is considered to be up to five in the field of view in females and up to three in males. In children, as well as expectant mothers, the same indicators are considered normal. When urinalysis according to Nechiporenko in one milliliter of it, four thousand leukocytes should be noted.

An increase in the number of white blood cells in the urine is called leukocyturia. A condition in which the number of leukocytes is more than sixty in the field of view is called pyuria. As a rule, this condition can be detected without a microscope, since the urine in such cases becomes cloudy. Plus, there are threads and flakes in it. Among the most common causes of an increase in the number of leukocytes in the urine, both children and adults, can be considered inflammatory pathologies of both the urinary tract and the kidneys. It can be both prostatitis, and acute or chronic pyelonephritis, urethritis, cystitis. In the case of inflammatory diseases of the urinary system, patients complain of pain during urination, as well as pain in the area above the pubis. With inflammatory pathologies of the kidneys, patients have an increase in body temperature, as well as a change in the color of urine. There are also cases when the number of leukocytes in the urine increases due to acute or chronic glomerulonephritis, tuberculosis or amyloidosis.

It should be noted that very often an increase in the number of white blood cells is observed when urine is not collected correctly for research. Most often, such errors are observed in the case when a person is not bothered by any symptoms that accompany certain pathologies. Both bacteria and leukocytes can enter the urine from the genital tract, so in order to determine a truly accurate number of white blood cells, one must first collect the urine correctly.

To do this, you must adhere to the following rules:

• It is necessary to collect urine only in a sterile vessel.
• Before collecting it, it is important to wash the genitals with plenty of soap and water.
• For women: before collecting urine, close the entrance to the vagina with a cotton swab. It is also important to slightly push the labia apart so that urine cannot come into contact with them when exiting.
• The first portion of urine must be poured
• In this case, only a medium portion of urine is needed.

Leukocytes in a vaginal smear

The detection of white blood cells in a smear is carried out using a microscope, namely at its high magnification. A little higher, we have already said that an increase in the level of white blood cells in the blood indicates the fact that an inflammatory or infectious process is taking place in the human body. The same goes for smear. In a normal healthy state, only single white blood cells can be detected in a woman's smear.

If they number in tens or hundreds, then one of the infectious pathologies of the vagina is on the face. It can be both thrush and vaginosis, colpitis and many others. The higher the level of leukocytes, the more powerful the infectious process. In all expectant mothers, the level of white blood cells in the urine must be constantly monitored, since it is in their case that an infection in the vaginal area can lead to tragedy. In pregnant women, the normal level of leukocytes in a smear is considered to be up to ten in the field of view. As a rule, along with an increase in the number of white blood cells in a smear, it is possible to detect an increase in the number of bacteria, as well as fungi, which in fact should not be in the vagina. If you are interested in more detailed information regarding leukocytes in urine, blood and smear, then you should make an appointment with a specialist who can answer all your questions.
