Polycystic Ovary Syndrome (PCOS) - Exams and Tests

No single test can show that you have polycystic ovary syndrome (PCOS). Your doctor will talk to you about your medical history, do a physical exam, and run some tests.

Medical history

The medical history includes questions about your symptoms. Your doctor may ask you about changes in your weight, skin, hair, and menstrual cycle. He or she may also ask you about problems with getting pregnant, medicines you are taking, and your eating and exercise habits.

You will also talk about any family history of hormone problems, including diabetes.

Physical exam

The physical exam checks your thyroid gland, skin, hair, breasts, and belly. You will have a blood pressure check and a pelvic exam to find out if you have enlarged or abnormal ovaries. Your doctor can also check your body mass index (BMI).


You may have a pelvic ultrasound, which might show enlarged ovaries with small cysts. These are signs of PCOS. But many women with PCOS don't have these signs.

Lab tests

You may have blood tests to check for:

Testing for problems from PCOS

Diabetes. If you have PCOS, experts recommend that you have blood glucose testing for diabetes by age 30.3 You may have this done at a younger age if you have PCOS and other risk factors for diabetes (such as obesity, lack of exercise, a family history of diabetes, or gestational diabetes during a past pregnancy). After this, your doctor will tell you how often to have testing for diabetes.
