摘要

The urine pregnancy test is one of the most useful methods for initially excluding pregnancy emergencies in the emergency department (ED). Although most urine pregnancy tests are regarded to be up to 99% accurate, false-negative results may lead ED physicians toward considering incorrect diagnoses, mask critical conditions, and even influence patient safety. Therefore, blood pregnancy tests (quantitative measurements) are clinically used for second-line screening. A double false-negative result from two pregnancy tests is very rare and has scarcely been reported for life-threatening ruptured ectopic pregnancy patients. In this report, for the first time, we describe a rare case of a 32-year-old female who suffered a life-threatening ruptured ectopic pregnancy and who had a double pregnancy test (both urine and blood) that was a false negative.
