The strategic advantages of neonatal diagnosis of sickle hemoglobinopathies depend on an accurate cord blood screening procedure. One hundred thirty-eight black children in whom a range of normal and abnormal hemoglobin genotypes was identified by agar gel and cellulose acetate hemoglobin electrophoresis at birth were retested by cellulose acetate three to five years later. The original cord blood diagnoses were verified in all 138, including all 26 with major sickle syndromes (SS, S-β thalassemia, and SC). Cord blood hemoglobin electrophoresis using these techniques permits accurate neonatal diagnosis of major and minor sickle hemoglobinopathies.
