What is the content of platelets in the blood of a healthy child?
The norm of platelets in the blood in children is one of the indicators of good hematopoiesis. The lifespan of these blood cells is small. On average, it is 7-10 days. Therefore, platelets must be constantly updated in the bloodstream to maintain homeostasis. Old cells are disposed of by the liver and spleen, and are excreted from the body together with other metabolic products.
Depending on the age of the child, the platelet count in his blood also changes. This is measured in units per millimeter cubic.
After blood sampling, it is centrifuged, separating the plasma, which then calculates the platelet count.
When deciphering the tests, doctors often use a table, which shows the norm of the content of platelets in the blood in children, depending on their age.
Thus, a newborn child in the blood contains 100-420 thousand platelets per mm cubic.
From 10 days of life and up to a year this indicator makes 150-350 thousand, at children older than 1 year - 180-320 thousand per mm of cubic blood.
What can raise and lower platelet levels in the blood say?
Quite often, for many reasons, a child's platelet count in blood may be higher or lower than normal. So, with increasing their content above the established norms, they speak of the development of thrombocytosis (the appearance of painful erythema accompanied by swelling of the fingers), and with a decrease in thrombocytopenia. The latter disease is characterized by increased fragility of the vessels and can lead to the development of subcutaneous hemorrhage at the slightest mechanical effect.
