Placenta Previa in Pregnancy (cont.)
IN THIS ARTICLE
Exams and Tests
Placenta previa is suspected when a woman in the 20th week of gestation or later reports having bleeding. An ultrasound examination (see below) is used to establish the diagnosis. The ultrasound examination is performed before a physical examination of the pelvis since the physical examination may lead to further bleeding.
Both transabdominal (using a probe on the abdominal wall) and transvaginal (with a probe inserted inside the vagina but away from the cervical opening) ultrasound evaluations may be performed, depending upon the location of the placenta.
