Thyroiditis | Diagnosis & Tests


How will my doctor know if I have thyroiditis?

Your doctor will perform laboratory tests to determine if you have thyroiditis, and, if so, what type of thyroiditis you have. Blood tests measure the amount of thyroid hormone in your blood and can indicate whether your thyroid is releasing too much hormone or too little. Blood tests can also show how much thyroid-stimulating hormone your pituitary gland is producing and what antibodies are present in the body.

Your doctor may also do a radioactive iodine uptake test to measure your thyroid's ability to take up iodine, a mineral that is needed to produce thyroid hormone. In some cases, a biopsy may be needed to determine what is attacking the thyroid.
