Serum Concentrations of Pregnancy-associated Proteins for Assessment of Gestational Age Before Abortion

Knowledge of gestational age (GA) is essential for guiding abortion care. In 2016, Gynuity Health Projects (GHP) launched a portfolio of research that aims to explore the possibility of developing a blood or urine test for this purpose.The goal of the present study is to validate initial study findings (protocol 8000) in a larger population of people seeking abortion. Staff will obtain a serum specimen from each participant before any cervical manipulation is performed and before any abortifacient drug is administered. The site will send the specimens to a central facility for storage until assay. Serum assays for PAPP-A and possibly other proteins will be performed at a selected laboratory by qualified experts.
