New blood test benchmarks for pregnant women could prevent dangerous clots

NCT ID NCT06133621

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at 100 pregnant women to determine normal ranges for a blood test called dRVVT, which checks for clotting problems. The goal is to better identify antiphospholipid syndrome, a condition that raises the risk of blood clots and pregnancy complications. By establishing reference values for healthy pregnancies, doctors can more accurately diagnose and manage at-risk women.

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 could help doctors better diagnose antiphospholipid syndrome in pregnant women, leading to improved monitoring and treatment to prevent complications like blood clots or pregnancy loss.
What could go wrong
This is a small, completed observational study that only establishes reference values. It does not test a treatment, so it cannot directly improve outcomes without further research.
