Secondary polycythemia

Secondary polycythemia is caused by the increased secretion of erythropoietin (erythropoietin) secondary to other diseases. It is characterized by the number of red blood cells, hemoglobin, hematocrit and total blood volume significantly exceeding the normal level. In childhood, when hemoglobin exceeds 160g / L (16g / dl), hematocrit exceeds 55% and the absolute value of erythrocyte volume per kilogram of body weight exceeds 35ml, the diagnosis can be made by excluding the relative increase of erythrocytes caused by blood concentration caused by acute dehydration or burn. Polycythemia can be divided into primary and secondary. Primary polycythemia vera; Secondary is mainly caused by tissue hypoxia.
