[Erythrocyte bilirubin determination (author's transl)].

The erythrocyte bilirubin value is of great interest in neonate pathology. Its sudden rising reflects the overbinding capacity to plasmatic albumin. A colorimetric, simple and accurate micromethod with 2-hydrazino-benzothiazol as reagent leads to its quantitative determination. Hemolysis interference is removed. The authors have determined a mean value of erythrocyte bilirubin/total plasmatic bilirubin ratio for newborn population without clinical or biological risks of kernicterus.
