Clinical significance of anti-AB titer of pregnant women with blood group O

Objective To detect anti-AB(IgG) in sera of the pregnant women with blood group O whose husbunds' is not O,then to explore its clinical significances.Methods 60 cases male donors with blood group O and 72 cases pregant women with different pregnancy times were detected by micro-column gel test(MGT).Results The positive rate of the male doners group were 18.3%(11/60).What was necessarily metioned was the rates were zero when their anti-A(IgG) or anti-B(IgG) less than 512 in sera;It was 52.8%(38/72) in the pregnant women group(in which,first-time pregnancy group was 47.4%,non-first-time pregnancy group was 58.8%).Statistics results indicated there were significant difference between male donors group and the pregnant women group(P0.01). Conclusion It was possible that there were relations between anti-AB(IgG) and pregnancy,and the latter(include abortion) could cause the former increase.There maybe were feasibilities to predict HDN or blood group for fetuses by dynamic detection of anti-AB(IgG).
