Clinical and laboratory aspects of reactive thrombocytosis in children
To determine the cause of thrombocytosis in the peripheral blood, the results of laboratory studies of children aged 8-15 years in two observation groups were analyzed: a) children with clinical manifestations of sinusitis after acute respiratory viral infections (12 people) b) children with reduced hemoglobin levels in peripheral blood (20 people ). Unified and automated hematological and biochemical research methods were carried out. Two main causes of thrombocytosis were established in the observation groups: the presence of a post-infectious inflammatory process, which was laboratory confirmed by an increase in acute-phase C-reactive protein in the blood serum; the presence of iron deficiency hypochromic anemia, which was laboratory confirmed by a decrease in serum iron and a decrease in hemoglobin in peripheral blood.
