胎盘绒毛的滋养层细胞分泌绒毛膜促性腺激素(Human Chorionic gonadotropin,简称HCG),经孕妇尿中排出。用羊红血球凝集抑制试验(简称血凝试验)半定量测定时,当每升尿中含312国际单位HCG即能较准确测出,可供临床诊断,妊娠和妊娠有关疾病及其疗效判断作参考。上海瑞金医院首用此法准确率99.24％。我室自1979年开始采用此法,共测5371人次,与临床诊断对照的准确率达99.38％。现就临床及实验室资料,对此法的临床应用作初步讨论。资料、方法与结果一、资料与结果: 1979-1982年孕尿HCG血凝法半定量测定5371人次,计稀释法4397及浓缩法974。受测对象:有停经,阴道出血或盆腔包块等症候而临床不能确定是否妊娠或妊娠有
Trophoblast cells of placenta villus secreted human Chorionic gonadotropin (HCG), excreted in the urine of pregnant women. With sheep hemagglutination inhibition test (referred to as the hemagglutination test) semi-quantitative determination, when per liter of urine with 312 international units HCG can be more accurately measured for clinical diagnosis, pregnancy and pregnancy-related diseases and their judgments for reference . Shanghai Ruijin Hospital first use this method accuracy of 99.24%. My room since 1979, this method, a total of 5371 people were tested, with the accuracy of clinical diagnosis of 99.38%. Now on clinical and laboratory data, the clinical application of this method for a preliminary discussion. DATA, METHODS AND RESULTS I. DATA AND RESULTS: Semi-quantitative determination of HCG in HCG from 1979 to 1982 was conducted for 5,371 person-times, including dilution method 4397 and concentration method 974. Subjects: menopause, vaginal bleeding or pelvic mass and other clinical symptoms can not determine whether the pregnancy or pregnancy have
