title: Comparison of serum and urine hCG levels with SP1 and PAPP-A levels in patients with first-trimester vaginal bleeding.
abstract: 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.
