How is miscarriage diagnosed?
A miscarriage can sometimes be diagnosed based on signs and symptoms. To help diagnose a miscarriage, your doctor can also perform tests. These may include: ultrasound, which produces an image of your body's internal structures and can be used to identify the presence of a foetal heartbeat and check that the embryo is developing correctly, or if a miscarriage has occurred; blood tests, which can be used to check the level of specific hormones, including human chorionic gonadotropin (HCG), that change during pregnancy or miscarriage; tissue tests, which involve the testing of pregnancy tissue that has been passed. Checking this in a laboratory can confirm that a miscarriage has occurred, and; a pelvic exam, to check if your cervix has begun to dilate, indicating a miscarriage.
