What is this test?
This test measures for reverse T3, which is the inactive form of the thyroid hormone T3. Reverse T3 is typically created in the body when the thyroid hormone T4 is converted into T3. Abnormal reverse T3 levels may point to a thyroid condition such as overactive or underactive thyroid. Reverse T3 may also be elevated in times of high stress, or as a result of illnesses not related to the thyroid.
Who is this test for?
This test is for anyone who may have a thyroid disorder. It can help present a clearer picture of thyroid health, as well as identify other important health markers. This test is typically ordered in conjunction with other thyroid tests, including the Free T3 Test, Free T4 Test, and the Complete Thyroid Panel.
