婴儿ABO血型定型的研究

ABO GROUP TYPING STUDIES IN INFANTS

分析４８７例１～１２个月婴儿ＡＢＯ血型鉴定的结果：正定型和反定型不一致者９６例，占１９．７％；血型难以判定者多为８个月内的婴儿（８６／３１６例，占２７．２％）；对３０例因血清缺乏ＡＢＯ抗体与正定型不合者采用加大血清量法鉴定，其中２４例（８０％）检查到与正定型一致的ＡＢＯ抗体；以低离子强度溶液法检查２１例正反定型不合者，其中１９例（９０．５％）正反定型达一致。研究提示，采用加大血清量法和（或）低离子强度溶液法可提高ＡＢＯ血型检定的准确性。

BO group typing was studied in 487 infants aged1～12 months. The discrepancies between red cell typ-ing and serum typing accounted for 19. 7 %, which wasoften observed in infants under 8 months of age. Wrongserum typing occured more often than wrong red celltyping. The research suggests that the metheds ofeither increasing serum volume or administrating lowionic strength solution to ABO group typing or of bothstrengthen the sensitivity of ABO group typing so as toget the accuracy for ABO group typing in infants andensure the safety of infantile blood transfusion in clinicalpractice.
