With the help of a 2 hour specific radioimmunological hCG determination (hCG-RIA), it is possible to demonstrate early pregnancy in cases where the normal pregnancy tests are still negative. The article reports on the use of this new rapid hCG determination in 500 gynecological cases which sought help for pain in the lower abdomen or vaginal bleeding. In connection with extrauterine pregnancy (51 cases) the serum hCG-RIA test gave positive results in 90% of cases, while a conventional pregnancy test via urine was positive in 13% of cases. Equivalent figures for patients with intrauterine pregnancy were 99% and 40% respectively. (author's)
