Determining the time required to achieve negative human chorionic gonadotropin value after a nonmolar pregnancy: preliminary results.

Objective: To determine the time of human chorionic gonadotropin (hCG) regression in nonmolar gestation.

Study Design: Patients treated at our institution between June 2012 and July 2013 were selected by a deterministic sequential sampling distributed among 2 phases. Distribution of the patients included resolved cases by vaginal delivery and cesarean section in preterm and term pregnancies, ectopic, and abortion.
