What tests can find the cause of abnormal uterine bleeding?
The tests your doctor orders may depend on your age. If you could be pregnant, your doctor may order a pregnancy test. If your bleeding is heavy, in addition to other tests, your doctor may want to check your blood count to make sure you don't have anemia (low iron) from the blood loss.
An ultrasound exam of your pelvic area shows both the uterus and the ovaries. It may also show the cause of your bleeding.
Your doctor may want to do an endometrial biopsy. This is a test of the uterine lining. It's done by putting a thin plastic tube (called a catheter) into your uterus. A tiny piece of the uterine lining is taken out and sent to a lab for testing. The test will show if you have cancer or a change in the cells. A biopsy can be done in the doctor's office and causes only mild pain.
Another test is a hysteroscopy. A thin tube with a tiny camera in it is put into your uterus. The camera lets your doctor see the inside of your uterus. If anything abnormal shows up, your doctor can get a biopsy.
