The rate of leukocytes in the blood of women, men,children

Update: December 2018 Human existence without immunity
is impossible. On the surface of our body lives a huge amount
microbes, we are confronted daily with dozens of viruses and harmful
factors (cold, stress, overheating, physical
перенапряжением и etc.). If the body was not protected from all
these effects, severe illness and death would not have forced themselves
to wait. White blood cells (white blood cells) – the most important component of this
protection that saves the life of man.

To determine the number of these cells is enough
total blood count. This indicator can significantly
change to a greater or lesser extent in various diseases.
Knowing normal white blood cell levels, even an ordinary person can
заподозрить наличие определенного diseases. However important
remember that only a doctor is able to diagnose correctly and
treat various pathologies.

What are leukocytes

This term refers to not just one specific cell, but about
a dozen different microscopic formations. Why are they called
in a word? Only because of their similar functions. Each of them
ensures the proper functioning of immunity, activated by
exposure to various harmful factors and the development of inflammation. For
better understanding, white blood cells can be divided into 4 large
groups:

white blood cells under the electron microscope

  • Эозинофилы. They perform two main functions.
    – participate in the development of allergies and pathological reactions,
    arising from the penetration of parasites (Giardia, Ascaris,
    Opistorch, Cysticerci and other organisms). Despite its
    unpleasant task, these cells are a necessary part of protection
    organism. It is they who can “give out” the underlying disease,
    causing specific symptoms;
  • Базофилы. The main culprits of any
    allergic reactions due to their histamine –
    amine compounds that activate inflammation. When penetrating
    susceptible organism of a certain substance (dust particles, dandruff
    animals, plant pollen, etc.), basophils release histamine.
    The result is the appearance of allergy symptoms (runny nose, dermatitis,
    anaphylaxis, edema, and others);
  • Neutrophils (сегменто- и палочкоядерные). With
    ingested harmful bacteria these cells will be the first to
    попытается ее уничтожить и предотвратить возникновение diseases.
    If they do not succeed – neutrophils inhibit infection before
    until the body develops specific antibodies against
    microbes and not destroy them. Also detect this component
    immunity is possible in any place where inflammation is actively developing,
    even if there are no bacteria there. This situation may occur when
    heart attack, burn, toxin poisoning and tissue necrosis;
  • Lymphocytes. This is the most complicated
    cells that last take part in protecting the body – in
    on average, after 2 weeks from penetration of the malicious agent.
    This time is necessary for lymphocytes to determine the exact type.
    threats and the production of antibodies that act only on a specific
    harmful factor. Another important cell function is
    providing antitumor immunity, the effectiveness of which
    low enough.

Additionally, doctors secrete monocytes as a special component.
immune system. However, changes in their quantity do not possess
very informative and recorded extremely rarely.

Normally, a blood test for leukocytes should show a certain
the number of each of these types of cells. Increase or decrease them
content, in most cases, indicates the presence of
disease or improper diagnostic procedure.

Normal leukocyte counts

The number of white blood cells is determined by the state
organism, therefore, when evaluating a blood test, it is necessary to consider
age and individual characteristics of each patient. Also,
normal values ​​may differ slightly in different
laboratories, depending on the equipment used. therefore
optimal values ​​for each indicator laboratory technicians print

The presence of deviations from normal values ​​in a large or
the smaller side is a reason to go to the doctor to find out the reason.
In most cases, changes in the blood are due to the presence of the disease.
or impaired immunity.

Withчины увеличения количества клеток

Exceeding the rate of white blood cells can detect when wrong
preparing for the analysis or on the background of the disease. In the first case,
the number of white blood cells increases slightly – not
более чем на 2*109 клеток/литре. In a healthy person
such changes are often observed with the following
states:норма лейкоцитов в крови

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

In other cases, abnormality of leukocytes in men or
women in a big way is considered a pathological sign. This
the indicator does not allow to determine the affected organ, however
reliably indicates the presence of inflammatory disease.
Why is this so important? At the first examination of the patient, it happens

seropositive arthritis. A blood test can ease a doctor’s task.
during the diagnosis.

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

Group of diseases Examples Why does cell count increase?
Bacterial or fungal infections (less often – viral)
  • Skin diseases (pyoderma, erysipelas, furunculosis and
    etc.);
  • Respiratory lesions (pharyngitis, tonsillitis, bronchitis,
    пневмония и etc.);
  • Intestinal infections (salmonella, escherichiosis, typhoid fever
    инфекция и etc.);
  • Urinary tract infections (pyelonephritis, cystitis,
    urethritis);
  • Neuroinfections (meningitis, encephalitis).
White blood cells are attracted to the focus of the disease and try
deal with a harmful microorganism. It requires
a large number of cells, so their blood levels can
rise significantly.
Autoimmune Diseases
  • Lupus erythematosus;
  • Scleroderma;
  • Rheumatoid arthritis;
  • Rheumatic fever (outdated name – rheumatism).
With these pathologies, the immune system is “mistaken” and the lymphocytes begin
attack your own tissue. During exacerbations, their number in
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 is responsible for almost any damage
inflammation. This процесс привлекает лейкоцитов из «депо».
Injuries
  • Fractures;
  • Any injuries (especially gunshot and contaminated);
  • Burns / acute frostbite.
Blood tumors
  • Leukemia;
  • Lymphogranulomatosis;
Blood is the same tissue as muscle, fatty tissue, or
connective tissue fibers. With uncontrolled growth occurs
multiple increase of its components (white bodies).

Excess blood leukocytes in women or men may
be an indirect sign of any of these conditions. To
narrow the “search range”, the doctor may recommend to determine
leukocyte formula. This is a special blood test that allows
estimate the number of different leukocytes (eosinophils, neutrophils and
etc.). As evidenced by the excess amount of each species
cells, you will learn below.

Eosinophils and basophils

These are the main indicators of allergies. The increase in their number
the presence of typical symptoms (rash, runny nose, swelling of the skin)
suggests this diagnosis with a high probability.
Reliably confirm it and identify the substance that caused
exacerbation of the disease, you can use allergoprob.

How are allergy tests carried out? There are several options.
of this analysis, but at present, the most practical
considered the scarification method. Its principle is as follows – on the skin
shallow scratches are applied and the most
common allergens (essence of dust, pollen, animal dander
и etc.). If there are signs of inflammation (significant
redness, swelling) – the sample is considered positive.

The second most common cause of increased eosinophils is
parasites. In Russia, most often these organisms cause
opisthorchiasis, ascariasis, enterobiosis, demodicosis, trichinosis, however
the development of more exotic diseases is also possible (leishmaniasis,
шистосомоза и etc.). It should be remembered that the increase in content
these cells is an indirect sign of parasitic pathology.
To confirm it, it is necessary to conduct additional
diagnostics.

Neutrophils

In most patients, neutrophil levels increase due to
the presence of a bacterial infection. It is this change of blood.
allows you to distinguish them from viral diseases and choose the right
healed tactics. Significant excess of the norm, often
indicates a serious illness and may become an indication
for hospitalization of a patient in a therapeutic hospital.

For other reasons, a large number of neutrophils can become
following pathologies:

  • Any damage to organs and tissues (heart attacks, cholecystitis,
    инсульты и etc.);
  • Serious injuries (fractures, burns and others);
  • Leukemia;
  • Poison poisoning (lead, mercury, animal poisons).

Lymphocytes

These cells leave the blood depot during the development of viral
diseases. As a rule, lymphocytes react slowly enough
their number begins to increase after a few days, and the first
antibodies appear no earlier than 1.5-2 weeks. None
however, this component of immunity is practically the only
virus protection. Also the level of lymphocytes may increase
during exacerbation of autoimmune pathologies, the presence of fungal infections
and leukemia.

Causes of Leukocyte Reduction

The improper work of immunity, first of all, affects
the number of white bodies. Reduction in blood levels
testifies to the weakened protection of the body and the presence
diseases. Most often to low leukocyte counts
приводят following pathologies:

Group of diseases The effect on the number of cells
Viral infections (influenza, RS-virus, norovirus, etc.) Some viruses can suppress natural immunity.
human, which is manifested by a deficiency of blood cells.
HIV

This вирус обладает особым действием на кровь человека, поэтому
it must be allocated to a separate group. HIV – хроническая
a disease that selectively affects human leukocytes and
leads to a decrease in their number. The longer the pathology takes
without adequate therapy – the worse the body’s defense.

How relevant is this problem? According to statistics from Roszdravnadzor,
This disease affects every 50th Russian. Unofficial
statistics (and probably more truthful) names other numbers –
каждый 10-ый человек в РФ болен HIV.

Therefore, when there is a shortage of white bodies without obvious
причины, пациенту следует обязательно сдать экспресс-тест на
this virus.

Severe conditions of the patient (with sepsis, severe pneumonia,
meningitis, etc.)
In these conditions, all functions of the body suffer, including
protective. Due to the strong damaging factor, immunity
unable to cope with it adequately and, as a result, gradually
exhausted. Deviation of blood parameters in the lower side – always
is an unfavorable sign.
Bone marrow damage (common osteomyelitis,
myelofibrosis and other pathologies)
Almost all blood cells are produced in the bone marrow.
Therefore, in case of violation of this process by any harmful factor –
there is a decrease in the number of blood cells
Violation of the production of white blood cells (after taking
cytostatics, chemotherapy, antiepileptic drugs,
radiation sickness)

Correctly identify and cure the cause of the decrease in the rate of white blood cells in
blood in children and adults can only qualified doctor.
Almost always, this deviation indicates a disturbed
work immunity. Therefore, when it is detected, it is recommended
turn to a specialist and not to engage in therapy
on their own.

Preparing for a blood test

In order to reliably determine how many leukocytes
contained in your blood, you must comply with the following
recommendations:

  • Hand over the analysis no earlier than 3 hours after taking
    food;
  • Within 3 hours, eliminate the use of caffeine and
    sugar-containing beverages, alcohol and tobacco;
  • Limit physical exertion for 30-40 minutes before delivery
    blood;
  • Do not take hot baths before going to hospital
    contrast souls and other water treatments with uncomfortable for
    body temperature.

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

FAQ
