目的 探索新生儿血型易误定的解决办法。方法 即刻离心法,4℃冰箱法,凝聚胺法,双人核对制。 结果 三种方法比较无凝者呈平行关系;即刻离心法为弱凝集或混合性外观者,4℃冰箱法可提高其灵敏度,凝聚 胺法可确定其血型,并经试验统计出了弱凝集或混合性外观的发生比率为6.2%;通过双人核对制可消除主观因 素。结论 凝聚胺法可消除即刻离心法中出现的弱凝集或混合性外观抗原较弱的客观因素,双人核对制避免了人 为主观错误。
Objective To explore the solution to the misidentification of neonatal blood type. Methods Centrifugation, 4 ℃ refrigerator method, polybrene method, double check system. Results Compared with non-coagulation, the three methods showed a parallel relationship. When centrifugal centrifugation method was used to detect weak agglutination or mixed appearance, the method of refrigerator at 4 ℃ could increase the sensitivity, coagulation-amine method could determine the blood type, and weak agglutination or Mixed appearance of the occurrence rate of 6.2%; through double check system to eliminate subjective factors. Conclusion Coagulation method can eliminate the objective factors of weak agglutination or mixed appearance antigens appearing in instant centrifugation. Double check system avoids human subjective errors.
