目的探讨检测血清β-HCG和孕酮在早期诊断异位妊娠中的作用。方法宫外孕及疑似宫外孕患者(观察组)24例,抽取血清用放射免疫法测定β-HCG和孕酮,选取正常早孕妇女20例作为对照组。结果以孕酮15 ng/m l为临界值,在观察组中鉴别宫内妊娠及异位妊娠的敏感度、特异度、准确度分别为90.91%、50%、87.50%。结论联合测定血β-HCG及孕酮值可作为一种异位妊娠快速辅助诊断的方法。
Objective To explore the role of serum β-HCG and progesterone in the early diagnosis of ectopic pregnancy. Methods 24 cases of ectopic pregnancy and suspected ectopic pregnancy (observation group) were included in this study. Serum was collected for determination of β-HCG and progesterone by radioimmunoassay. Twenty normal pregnant women were selected as control group. Results The sensitivity, specificity and accuracy of progesterone 15 ng / m l were 90.91%, 50% and 87.50% respectively in the observation group for differentiating intrauterine pregnancy and ectopic pregnancy. Conclusion Combined determination of serum β-HCG and progesterone values can be used as a rapid auxiliary diagnosis of ectopic pregnancy.
