Unfortunately, a few tests are required to diagnose the placenta's cyclopretum. The first test is a radiation scan. You can see a clear image inside the body. You can also run a blood test, such as a blood test to check blood clotting. You can make clear the structure of the placenta and the uterus through an ultrasound.
Doctor, I think there's a placental cyclotoma, and the peritoneal cortex continues to bleed.
