Abstract:
【Objective】 To investigate the positive rate of platelet antibody in pregnant women and analyze the related factors. 【Methods】 A total of 620 pregnant women who underwent antenatal examination from March 2017 to July 2018 were screened for platelet antibodies by solid phase agglutination method. The relationship between platelet antibody positive rate and blood transfusion history, reproductive history and ABO blood group were analyzed, and the profile of disease were alsodiscussed. 【Results】 55 out of 620 pregnant women presented positive platelet antibody, with a positive rate of 8.87%.The platelet antibody positive rate of pregnant women with ahistory of blood transfusion (14.13%) was higher than those never transfused before(6.65%), and the platelet antibody positive rate of pregnant women with a childbirth history (10.46%) was higher than those didn′t bear before(3.52%), showing statistically significant differences (P<0.05). The ABO blood grouphad no correlation with antenatal platelet antibody positive rate(P>0.05). Pregnant women with positive platelet antibodies mainly suffered from diseases such as placenta pravia, scarred uterus, placental implantation and thrombocytopenia. 【Conclusion】 Blood transfusion history, reproductive history and disease type have certain effects on the positive rate of platelet antibody in pregnant women.Screening platelet antibody in pregnant women is of great significance to prevente and reduce miscarriage during pregnancy and the occurrence of neonatal alloimmune thrombocytopenic purpura(NAITP).
