[The excretion of chorionic gonadotropin in ectopic pregnancy (author's transl)]

In 244 cases of ectopic pregnancy the excretion of chorionic gonadotropin in the urine was determined in 459 tests. In 88% of the cases an immunologic pregnancy test (pregnosticontest) was positive. The mean quantitive excretion of chorionic gonadotropin in the urine was 20 +/- 13% of the values for normal pregnancy. In 11.4% of the cases, values compatible with the chorionic gonadotropin excretion in normal intra-uterine pregnancy were observed. Repeat quantitative tests on the same patient showed a decrease of the mean chorionic gonadotropin titre in the urine with increasing gestational age. The results are shown in diagrams.
