ABO hemolytic disease of the newborn without hyperbilirubinemia is described in 17 full-term infants. The erythrocyte characteristics, such as reticulocytosis, microspherocytosis, and positive indirect antiglobulin (Coomb's) test, resembled those in ABO disease with hyperbilirubinemia. Erythrocyte acetylcholinesterase activity was reduced in this group to the same degree as in the more severely affected infants. Negro infants predominated over white, in a 2.5:1 ratio in this mild ABO group.
17例足月儿被诊断为无高胆红素血症的新生儿ABO溶血病。其红细胞特征，如网织红细胞增多、小球形红细胞症以及间接抗球蛋白（库姆斯）试验阳性，与有高胆红素血症的ABO疾病相似。该组患儿的红细胞乙酰胆碱酯酶活性降低程度与病情更严重的患儿相同。在这个轻度ABO组中，黑人婴儿数量超过白人婴儿，比例为2.5:1。
