The general analysis of a blood - decoding at children

This type of laboratory study, like a general blood test (KLA), occupies one of the central places in the diagnosis of a huge number of diseases. After all, any violation entails the reaction of the body, in particular - the change in the composition and characteristics of the individual components of the blood.

This type of research is conducted almost from the moment of birth. So, during the first year of life, the baby will have to give it at least 3 times, and if there is any disease, then more often.

The interpretation of the results of the general analysis of blood in children and comparison with the norm should only be performed by a doctor. After all, a change in one or another indicator, in itself, can only be a sign of a disease. Therefore, in order to draw the right conclusion and prescribe the necessary treatment, many other factors (chronic diseases, hemopoiesis disturbances, etc.) must be taken into account.

How do the norms of general analysis vary by age and what are the deviations?

So, when deciphering a general analysis of blood in children, doctors rely on the leukocyte formula, which corresponds to the age of the child. It reflects the ratio of all forms of leukocytes (neutrophils, lymphocytes, monocytes, eosinophils, basophils). In addition to leukocytes, the UAC indicates the content of red blood cells, hemoglobin and platelets and ESR (erythrocyte sedimentation rate).

When carrying out a general blood test in children and deciphering it, they pay particular attention to ESR, which normally has the following meanings:

• newborn infants: 2-4 mm / h;
• children up to one year and older: 4-10.

The thing is that with the development of a pathological process in the body, in particular of a viral or infectious nature, the first changes in the analysis is the ESR. In such cases, as a rule, this parameter assumes greater values ​​than in the norm.

Also pay attention to the content of hemoglobin in the blood of a child. Its deficiency can indicate a violation such as anemia or anemia. In such a situation, the child may lose activity, lose appetite, older children may complain of headaches and dizziness. With this symptomatology, the first thing doctors prescribe is a general blood test.

Thus, such a method of laboratory diagnosis, as a general blood test, simply can not be underestimated. It is with the help of it at an early stage that it is possible to presume a violation and to appoint an additional examination in this regard.
