已有人报告妊娠终止和羊膜穿刺后,胎-母出血(FMH)可能引起母血甲胎蛋白(AFP)上升。阴道分娩期经常发生经胎盘的 FMH。作者用敏感的AFP 试验测量分娩前、后母血 AFP 变化,以检测FMH,并将这些资料和用 bmc 试剂装置的酸洗提技术检测的胎儿红细胞变化相比。71例在作者医院单胎足月自然分娩或引产的病人参加本研究。分娩时平均孕龄39.7周。分娩前、后用 bmc 试剂设备进行酸洗提技术检查 FMH,同时测量41例 AFP 浓度。分娩前取母静脉血,分娩后尽快收集第二次血标本。根据化验中变化的系数
It has been reported that fetal-maternal hemorrhage (FMH) may cause a rise in maternal alpha-fetoprotein (AFP) after termination of pregnancy and amniocentesis. Placental FMH often occurs during vaginal delivery. The authors used a sensitive AFP test to measure maternal AFP changes before and after childbirth to detect FMH and compare these data with changes in fetal erythrocytes detected by acid-stripping techniques using a bmc reagent device. 71 cases of single birth in the author’s hospital full-term childbirth or induction of labor in patients with this study. The average gestational age at delivery was 39.7 weeks. Before delivery, bmc reagent equipment for pickling to check the FMH technology, while measuring 41 cases of AFP concentration. Maternal blood taken before delivery, collection of blood samples as soon as possible after delivery. According to the changes in the test coefficient
