Could a routine blood test flag a dangerous pregnancy complication?
NCT ID NCT07826247
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Placenta accreta spectrum is a serious pregnancy complication where the placenta grows too deeply into the uterus, risking severe bleeding during delivery. Doctors usually rely on ultrasound to detect it, but ultrasound accuracy varies. This study checks whether simple blood tests taken on hospital admission can help predict which mothers with placenta previa and a prior cesarean delivery will develop the condition. Researchers compare blood test results with the actual diagnosis confirmed at delivery.
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 the blood markers prove reliable, doctors could use a routine blood test alongside ultrasound to flag high-risk pregnancies earlier and plan safer deliveries.
- What could go wrong
- This is an observational study, so it can only show whether markers correlate with placenta accreta, not whether acting on them improves outcomes. The findings may not hold up in other hospitals or patient groups.

Who is studied
The study population consists of pregnant women aged 18 to 40 years presenting to the Women's Health Hospital at Assiut University. Eligible participants must have a singleton pregnancy at a gestational age greater than 28 weeks, a diagnosis of placenta previa confirmed by ultrasound, a history of previous cesarean delivery, and be hemodynamically stable upon admission. Patients will be excluded if they present with intrauterine fetal demise (IUFD), intrauterine growth restriction (IUGR), premature rupture of membranes (PROM), chorioamnionitis, known blood diseases or bleeding tendencies, hypertension, or diabetes mellitus.
