Norms of blood tests in children. Decoding and features of collection

A general blood test (abbreviated as KLA) is perhaps the main method of examination, which helps diagnose most diseases. The popularity of the study is determined by the relative simplicity of its conduct and the possibility of obtaining a quick result, so that it is possible to establish the cause of a disease in the shortest possible time. What are the norms of blood tests in children and how to properly take them? We will try to answer this question.

UAC in children. What is it for?

Thanks to this study, you can determine the following parameters of the child's condition:

• Number of erythrocytes, platelets, white blood cells;
• Hemoglobin level ;
• The ratio of erythrocytes to plasma;
• Sedimentation rate of erythrocytes (ESR).

Preparation for analysis

To get a reliable result, you should prepare the baby. So, the general analysis of the blood in children, however, as in adults, is taken exceptionally in the morning on an empty stomach. Therefore morning feeding and even a small drink in this case are excluded. Also it is not recommended to take any medications on the eve, except for critical cases. Since it is difficult for babies to withstand large gaps between feedings, it is permissible for such children to submit the analysis after a while (two to three hours) after the child has eaten.

How It Works

Blood is taken from the finger using a scarifier tool. The laboratory assistant performs a puncture of the skin on the finger, from which the blood appears. Using a pipette, it is collected in a special vessel.

Norms of blood tests in children

After carrying out of laboratory research there comes a turn of interpretation of results. Before considering the norms of blood tests in children, it should be noted that the following indicators reflect the normal values for a one-year-old child. Due to the rapid growth of the baby, the different speeds of metabolic processes, the results of the study can seriously differ. Therefore, the norm of blood analysis in children for each age, and also depending on gender, is different.

1. Hemoglobin . The parameters of the norm are 110-135 g / l. Greater hemoglobin content may indicate heart disease, thickening of the blood. The low content is characteristic for anemia.
2. Erythrocytes . The norm is 3.6-4.9 x 10 ¹² / l. A low value indicates a lack of iron, protein and vitamins. Increased may be a sign of hypoxia and blood clots (depending on whether the value is absolute or relative).
3. Platelets . The norm frames are wide enough - from 180 and up to 400 x 10 ⁹ / l. A larger number of platelets indicates a possible inflammation in the body and is a characteristic condition after operations. Reduction of platelets is observed in newborns in case of prematurity.
4. Erythrocyte sedimentation rate . The normal value is 4-12 mm / h. Increased sedimentation rate is observed with inflammatory processes in the body, intoxication, infections, kidney diseases. A lowered value may appear due to weight loss, starvation.
5. Leukocytes . Leukocytosis (increased number of leukocytes) occurs with acute inflammation, tumors, burns. Leukopenia (a lower value) is a consequence of starvation, a physiological condition, can be hereditary in nature. The norm is 6.0-12.0 x 10 ⁹ / l.

It should be noted that the above norms of blood tests in children are conditional, and each specific analysis requires mandatory interpretation by the treating pediatrician.
