Abstract
When human chorionic gonadotropin (hCG) level is above the discriminatory value of 1500 IU/L, but no intrauterine pregnancy is visible on transvaginal ultrasound (TVUS), options such as a complete/incomplete abortion, multiple gestation, or heterotopic gestation should be considered. hCG level below the discriminatory zone in the absence of an intrauterine sac is inconclusive. In hemodynamically stable patients, repeated beta-hCG and TVUS exams are recommended. It is important to note that the discriminatory values of serum hCG for the diagnosis of an intrauterine pregnancy are not always reliable. Failure to recognize an intrauterine pregnancy may be more harmful than delaying diagnosis of an extrauterine pregnancy.
