Could a simple home urine test replace daily clinic visits for pregnancy of unknown location?
NCT ID NCT06802263
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study is testing whether an at-home urine test can accurately measure hCG levels in women with a pregnancy of unknown location (PUL). Participants will collect their first morning urine at home and compare it to a blood test done at a lab. If the home test proves accurate, it could allow women to monitor their condition from home, reducing the need for frequent clinic visits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- at-home quantitative urine b-hCG test
- What this could lead to
- If successful, this could allow women with pregnancy of unknown location to monitor their hCG levels at home, reducing the need for daily clinic visits.
- What could go wrong
- This is a small pilot study with only 35 participants, so results may not apply to everyone. The test requires strict preparation (e.g., limiting water) which may be difficult for some.
