[Novel immunoassay for laboratory assessment of the erythron state].

The paper presents the results of a study of embryonic or primitive hemoglobin (HbP), by using the authors' developed immunodiffusion monovalent test system in the neonatal umbilical blood and in girls than in the boys. HbP was also detected in patients with erythema (66.7%) and acute myeloleukemia (22.22%), it was absent in those with chronic lympholeukemia. The findings suggest that the early antenatal type of hemoglobin is likely to be of diagnostic value in assessing the degree of hypoxia in the differential diagnosis of hemoblastoses.
