RESUMEN
OBJECTIVES: The ideal assessment after mifepristone and misoprostol for undesired pregnancy of unknown location (PUL) is unknown. STUDY DESIGN: We prospectively followed patients at Planned Parenthood League of Massachusetts (2019-2021) with PUL who received immediate mifepristone and misoprostol with serial at-home urine pregnancy tests (UPT) and in-office serum HCGs. RESULTS: Of 13 patients, 10 had a successful medication abortion. For those who completed UPTs (N = 9), all were negative by Day 14. Two abnormal pregnancies had positive UPTs on Day 14. CONCLUSION: A negative UPT on Day 14 may help determine complete abortion after medication abortion for undesired PUL. A positive UPT on Day 14 warrants further evaluation. IMPLICATION: Patients taking mifepristone and misoprostol in the setting of undesired PUL who cannot access serum testing may consider an at-home UPT to confirm complete abortion.
