What are the tests for placental abruption?

Not many: It is a clinical diagnosys. Unusual abdominal pain, vaginal bleeding, uterine contractions. Sometimes if the abruption is severe and ultrasound can see it. The baby can suffer as well showed by a non reassuring fetal strip. Sono finds abruption only in 30% of cases in average.

Ultrasound, monitor: Abruption is a bleed from the placenta; a disruption of either the mother or baby's blood supply. Many causes: trauma, high blood pressure, drugs (cocaine), preterm labor, polyhydramnios. Can be very large or very small, so even US can miss a diagnosis. Symptoms: usually preterm contractions, sometimes vaginal bleed. Fetal monitoring is necessary. Wait, watch; abruption can self-heal sometimes.
