Objective:
To explore hCG patterns using multi-level urine pregnancy tests (MLPTs) among prenatal clients to evaluate the potential use of these tests for medical abortion follow-up after 63 days' gestation.
Study Design:
Prenatal clients with gestations 9-12 weeks were asked to administer an MLPT weekly for three weeks. We evaluated change in hCG range over one- and two-week intervals.
Results:
Our analysis included 121 clients. Over one-week intervals, 26.5-43.1% of participants had a drop in hCG range. The proportion with a decline after two-weeks was 42.0-48.3%.
Conclusion:
This follow-up strategy would not work in gestations beyond 63 days.
