Defining the curve when initial levels of human chorionic gonadotropin in patients with spontaneous abortions are low. Academic Article uri icon


  • Because lower initial hCG concentrations are associated with slower rates of decline in spontaneous abortions, the aim of this study was to provide a detailed description of the expected rates of hCG decline in patients presenting with very low initial hCG levels and who ultimately were confirmed to have spontaneous abortions. When initial levels lie between 50 and 500 mIU/mL, the slowest expected percentage decline ranges from 12% to 24% in 2 days and from 34% to 68% in 7 days.
