[Comparison between immunological pregnancy test and ultrasonic examination for determination of early pregnancy (author's transl)].

Ultrasonic B-scan examination (Vidoson) and the Gravimun semiquantitative HCG test were applied simultaneously to 107 women, between the 35th and 95th day form menstruation. Control checks were made after another ten and 20 days. The findings so far recorded are likely to support the conclusion that the sensitivity of ultrasonography is higher than that of semiquantitative detection of HCG from urine and, therefore, more applicable to diagnosis of early pregnancy or assessment of disorders in early pregnancy.
