Can a blood test predict dangerous Post-Birth bleeding?
NCT ID NCT03413917
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study analyzed tissue and blood samples from 21 women to find genetic markers that might predict uterine atony, a condition where the uterus fails to contract after childbirth, leading to severe bleeding. The goal was to identify women at risk so doctors can take preventive steps. No treatment was tested—this was purely a discovery study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could point toward a way to identify women at risk for uterine atony before they give birth, potentially preventing dangerous bleeding.
- What could go wrong
- This was a very small, early study (21 participants) that only looked for markers—it did not test any treatment. The findings may not lead to a practical test or apply to all women.
