[Differential diagnosis of unconjugated hyperbilirubinemia].

Eighty-four patients with unconjugated hyperbilirubinemia were examined for erythron. The authors managed to reveal a group of patients with evident signs of the derangement of the nucleus-containing cells of erythropoiesis which was manifested in the accumulation of SIA-positive material in the cytoplasm and by the presence of morphological abnormalities in the peripheral red blood cells.
