Abstract:

Serum chorionic gonadotropin was measured weekly in 12 women from the time of legal first-trimester abortion until values were below 10 IU. The elimination followed a 2-component curve. The half-life in the first few days was 1.1 day, hereafter 4.2 days. Serum HCG decreased to less than 10 IU within 22-40 days. The elimination of serum HCG was found to decrease so uniformly that values which do not decrease must be considered abnormal. A sensitive bedside urine HCG test was found to be positive from 13-31 days after the abortion. (author's) (summaries in DAN, ENG)
