We compared the performance of two immunologic tests for hCG in urine with a qualitative serum hCG assay. The latex agglutination assay ( Sensi -Tex) was found to be superior to a hemagglutination assay (Beta-Stat) in that fewer equivocal results were obtained with it. Excluding equivocal results, both urine tests agreed well with the results of the serum qualitative hCG assay. Interference by human menopausal gonadotropins occurred at higher concentrations with Sensi -Tex than with Beta-Stat, suggesting that the Sensi -Tex reagents have greater specificity. We recommend that laboratories examine the performance of available urine pregnancy tests on site before selecting a reagent system for routine use.
我们将两种尿hCG免疫检测方法的性能与血清hCG定性检测进行了比较。结果发现，乳胶凝集试验（Sensi-Tex）优于血凝试验（Beta-Stat），因为前者产生的可疑结果较少。排除可疑结果后，两种尿检测方法与血清hCG定性检测结果高度一致。人绝经期促性腺激素对Sensi-Tex的干扰在较高浓度时出现，而对Beta-Stat的干扰则在较低浓度时出现，这表明Sensi-Tex试剂具有更高的特异性。我们建议实验室在选择常规使用的试剂系统之前，先在现场检测现有尿妊娠试验的性能。
