How to Test for Graves' Disease
The only way to truly know whether you have Graves' disease is to visit your doctor and allow him to test your thyroid, looking for any suspected conditions. You'll first undergo a simple blood test to see the levels of thyroid-stimulating hormone (TSH) and thyroxine in your body.

Consider having a radioactive iodine-uptake test to confirm Graves' disease. You will be given a small amount of radioactive iodine, which will later be measured in your thyroid gland. A high uptake of radioactive iodine indicates Graves' disease while low uptake occurs in other hyperthyroidism conditions.

Expect your doctor to test your thyroglobulin (Tg) levels. Elevated Tg occurs in patients with Graves' disease. Your Tg levels could also indicate thyroid cancer, which is always suspected with any thyroid problem.

Follow up with testing every 2 to 3 months after diagnosis. Additional blood tests will determine how well your treatment is going.

Tips & Warnings
Home thyroid tests are available, with results sent from a certified lab. Such tests should not serve as a replacement for visiting your doctor.
Graves' disease tends to run in the family, so your doctor will ask for a complete medical history. You should know at least your immediate family's medical history before you go to the doctor.
