有人报告异位妊娠者子宫直肠陷窝血中绒毛膜促性腺激素(hCG)水平比外周血明显高。用放射免疫法(RIA)测定 hCG 时,蛋白水解酶能使之假性升高。作者报告此文是为了证实以前的发现及消除子宫直肠陷窝血中出现蛋白水解酶 hCG 水平出现假性升高的可能性。如果子宫直肠陷窝血中 hCG显著升高,那时常规测量可增加 hCG 在诊断异位妊娠中的灵敏度。作者在常规筛选异位妊娠时,于子宫直肠陷窝处取血样26份,同时取外周血。用 RIA双抗体测定 hCG。4份血样(陷窝及外周血)在刀
It was reported that uterine ectopic pregnancy in patients with ectopic lacunar blood chorionic gonadotropin (hCG) levels were significantly higher than in peripheral blood. When measuring hCG by radioimmunoassay (RIA), the proteolytic enzyme makes it falsely elevated. The authors report this article to confirm previous findings and to eliminate the possibility of a false rise in proteoglycan hCG levels in the uterine rectal lacunar blood. If the hCG in the uterine rectum lacunar blood is significantly elevated, then the routine measurement can increase the sensitivity of hCG in the diagnosis of ectopic pregnancy. In the routine screening of ectopic pregnancy, the uterus in the rectum lacuna 26 samples were taken, while taking the peripheral blood. HCG was measured with RIA diabody. Four blood samples (lacunar and peripheral blood) were on the knife
