A free or total triiodothyronine (free T3 or total T3) test is used to assess thyroid function. It is ordered primarily to help diagnose hyperthyroidism and may be ordered to help monitor treatment of a person with a known thyroid disorder.
Higher-than-normal T3 levels typically indicate hyperthyroidism (overactive thyroid). Hyperthyroidism has several causes, including Graves' disease (an autoimmune condition), thyroid nodules and thyroiditis (inflammation of your thyroid gland).
