Clinical evaluation of a sensitive urine pregnancy test in the gynecological emergencies.

A rapid sensitive urine pregnancy test (SPT) using monoclonal antibody against human chorionic gonadotropin and a conventional urine pregnancy test (GPT) were performed in 364 women attending 'Gynecological Emergencies' for lower abdominal pain and/or vaginal bleeding, aiming at early detection of ectopic and intra-uterine pregnancy-related disorders. The overall incidence of a positive test was 24%. In 42 patients, with histopathological evidence of ectopic pregnancy, SPT was positive in 41 (98%), while GPT only in 19 (45%). In 47 patients with evidence of intra-uterine pregnancy-related disorders, SPT was positive in 45 (96%), while GPT in 33 (70%). The sensitive urine pregnancy test can improve significantly the efficiency of the early diagnosis of ectopic and intra-uterine pregnancy-related disorders, and can be used as a screening method for patients having even in the slightest way suspect of having an ectopic pregnancy.
