Abstract
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.
