ABSTRACT
Objective To understand the neonatal ABO type positive and reverse typing consistent rate and to improve the accu-racy of the methods of neonatal blood.Methods The traditional tube method was used to detect the local neonatal ABO blood.The method of micro gel cards,improved tube method,enhancer and traditional tube method,paper,micro-plate,polybrene method to de-tect anti A,anti B,anti D titer,and neonatal blood detection comparator.Results Neonatal ABO positive and negative stereo types compliance rate was 83% (913/1 100);Detecting 15 copies of anti A,B,D titer,the highest sensitivity was improved intensifier tube method and the worst is the method of paper.The method of neonatal specimens was with the similar results.Conclusion ABO positive and negative stereo types should be increased by plasma (serum)levels and extending the incubation time,or using theen-hancerof this study,thereby improving the accuracy of the newborn blood testing.
