Leukocyte blood count

Modern diagnostics has gone a long way, but the proven old research methods have not become less informative. So, thanks to a blood test, doctors get information about changes in the body. These include leukocyte blood count, the decoding of which will help to learn about possible diseases.

Decoding of blood leukocyte count

Decoding of blood leukocyte count

Leukocytes are called one of the blood cells. These are white blood cells. It is established that they provide the elimination of infections and foreign bodies in the body. If the concentration of white cells in the blood is normal, it can be assumed that the immune system successfully resists viruses and bacteria. If this is not the case, then there is a need to seriously think about strengthening the immune system. General clinical blood analysis with decoding of leukocyte formula gives you the opportunity to have an idea about the presence of viral or bacterial infection. The test is based on determining the quantitative composition of leukocytes in the blood plasma. In the results of analyzes, this indicator is designated by the Latin abbreviation - WBC, which corresponds to the initial letters in the words white blood cells in English.

A large concentration of them in the composition of the uniform elements indicates the presence of an infectious focus in the patient. In contrast, a reduced number of white cells is evidence of depression of the immune system by some disease. Usually in such cases, a person experiences general weakness and fatigue.

It should be noted that leukocytes are heterogeneous in their composition, rather, it is a group of cells represented by:

  • b lymphocytes;
  • neutrophils, from which emit segmented and stab;
  • basophils;
  • eosinophils;
  • monocytes;
  • plasma cells.

All of the listed types of white blood cells are leukocyte blood form, which, in comparison with the norm, can be interpreted to reveal pathologies in the body.

Norm indicators in children

Interpretation of blood leukocyte count in children

Depending on the age of the patient, the indicators for decoding the formula will vary. Speech in this case is about age gradation. Childhood leukocyte concentrations are significantly different from similar data decoding in adults. The concentration of WBC bodies in pediatric blood is much higher and with the development of the child is constantly changing, acquiring a normal value by the age of fifteen.

The highest rate is retained in the blood of infants up to six months. Its level reaches 72-74%. But this is a normal phenomenon and is not considered a cause for concern of parents if the baby feels well on all outward signs. The tables show the indicators of the children's norm of white blood cells depending on the age category, as well as the interpretation of the leukocyte formula.

Results in men and women

Decoding leukocyte blood in men and women

The concentration of white blood cells in women and men is in the range of 20-40%. If the results of laboratory studies correspond to the generally accepted norm, then this confirms the absence of infection of the organism. Under normal concentration of white blood cells in the patient's body is meant the range from 4 × 10⁹ / l to 9 × 10⁹ / l. The formula at the normal level of its components in adults is the following indicators.

What do abnormalities mean?

What do abnormalities in leukocyte blood count say

An excess of the norm by leukocytes leads to a condition called leukocytosis. Pathology provoke:

  • acute bacterial infections;
  • various viral diseases;
  • inflammatory processes;
  • purulent abscesses;
  • increased body sensitivity to certain substances;
  • bleeding;
  • renal dysfunction;
  • insulin dependence up to deep coma;
  • cancer;
  • burns.

Leukopenia is a condition of the blood with a reduced level of white blood cells. It happens with such pathological changes in the body as:

  • radiation exposure;
  • blood disorders;
  • cancer of the blood-forming organs;
  • systemic disorders in the functioning of the body's immune defense;
  • anorexia;
  • hypotension.

The blood leukocyte formula carries enough information, but has a wide range of suspected diseases. To establish an accurate diagnosis, it is necessary to use other diagnostic methods.
