Serum levels of human chorionic gonadotropin (hCG) in patients with threatened abortion are compared to the values in normal pregnancy. The predictive value was 93%, the sensitivity was 84%, and the prediction of gestational viability was 81% for the threatened group. These results compare favorably with urinary pregnancy testing and are similar to those obtained with the assay of Schwangerschaftsprotein I. Human chorionic gonadotropin was, however, a much better predictor of pregnancy outcome than pregnancy-associated plasma protein-A.
将先兆流产患者的血清人绒毛膜促性腺激素（hCG）水平与正常妊娠患者的水平进行比较。对于先兆流产组，预测值为93%，敏感性为84%，妊娠存活预测率为81%。这些结果优于尿妊娠试验，且与妊娠特异性β1糖蛋白检测结果相似。然而，与人妊娠相关血浆蛋白A相比，人绒毛膜促性腺激素对妊娠结局的预测要好得多。
