title: Ectopic pregnancy. What to do during the 20-day window.
abstract: An analysis of serial serum human chorionic gonadotropin (hCG) levels in 357 pregnant women revealed that the rise in hCG in normal intrauterine pregnancies differed from that in both ectopic gestations and abnormal intrauterine pregnancies. However, measurement of serial hCG levels cannot differentiate an ectopic from an abnormal intrauterine pregnancy. A protocol was developed for the management of patients with suspected ectopic pregnancy before ultrasound can reliably confirm an intrauterine gestation.
