    This test is to determine the amount of Reverse T3, one of the two forms of T3 produced by the body. When the body is under stress, instead of converting T4 into T3 - the active form of thyroid hormone - the body conserves energy by making what is known as Reverse T3 (RT3), an inactive form of the T3 hormone. The value of RT3 tests in diagnosis is controversial, as some practitioners believe that the body continues to manufacture RT3 instead of active T3, causing various symptoms that are identified as the so-called “Wilson’s syndrome.
