目的通过对53例怀疑为异位妊娠患者的血清β－hCG放免分析，评价β－hCG对异位妊娠的诊断价值。方法用卫生部上海生物制品研究所提供的“人绒毛膜促性腺激素－B亚基（β－hCG）放免测定药盒（双抗体法）”测定患者血清β－hCG值。以本院正常值（n=130）β-hCG（0．lnmol／L）为诊断标准。结果38例异位妊娠中35例阳性，15例非异位妊娠12例明性。用β－hCG诊断异位妊娠的灵敏度、特异性和准确性分别是92．1％、80．0％和88．7％。结论怀疑异位妊娠时测定血清β－hCG有重要价值。
Objective To assess the value of β-hCG in the diagnosis of ectopic pregnancy by analyzing the serum β-hCG in 53 cases of suspected ectopic pregnancy. Methods Serum β-hCG levels were determined by “human chorionic gonadotropin-B subunit (β-hCG) radioimmunoassay kit (double antibody method)” provided by Shanghai Institute of Biological Products, Ministry of Health. Normal hospital (n = 130) β-hCG (0.lnmol / L) as the diagnostic criteria. Results 38 cases of ectopic pregnancy in 35 cases were positive, 15 cases of non-ectopic pregnancy in 12 cases of clear. The sensitivity, specificity and accuracy of β-hCG in the diagnosis of ectopic pregnancy were 92.1%, 80.0% and 88.7%, respectively. Conclusions There is an important value in the determination of serum β-hCG during ectopic pregnancy.
