输卵管妊娠是妇科常见急腹症之一，当输卵管妊娠流产或破裂急性发作时，可引起腹腔内严重出血。按常规做尿妊娠试验及血ＨＣＧ－β定量测定，但发现这两种方法各有其不足，因此我们选择２０例患者的后穹窿穿刺液做妊娠试验，并与上述两种方法进行比较，其结果尿妊娠试验假阴性较多，只能做为参考。而放免法做血ＨＣＧ－β测定虽然结果准确，但所需时间较长（２．５小时），只有后穹窿穿刺液做妊娠试验结果与临床诊断完全一致，符合率为１００％，且后穹窿穿刺液中ＨＣＧ－β的含量明显高于尿中ＨＣＧ－β的含量，这就进一步证明了后穹窿穿刺液做妊娠试验比尿液做妊娠试验更有诊断价值，且具有方法简单、快速（５分钟）、重复性好等优点，适用于急诊检测。
Tubal pregnancy is one of the common gynecological acute abdomen, tubal abortion or rupture when the acute attack can cause severe intra-abdominal bleeding. According to conventional urine pregnancy test and blood HCG-β quantitative determination, but found that the two methods have their own deficiencies, so we choose 20 patients with posterior fornix puncture fluid to do pregnancy test, and compared with the above two methods, its Results urine pregnancy test false negative more, can only be used as a reference. The radioimmunoassay of blood HCG-β determination although the results are accurate, but the time required for a longer (2.5 hours), only the posterior fornix puncture fluid to do the pregnancy test results and clinical diagnosis exactly the same, the rate was 100%, and the posterior fornix The content of HCG-β in the puncture fluid was significantly higher than that in the urine, which further proves that the posterior fornix puncture fluid is more diagnostic than the urine pregnancy test and has the advantages of simple and rapid method (5 Minute), good repeatability, etc., suitable for emergency testing.
