Overview

The reverse T3 test has to be done at the same time you do the free T3, and you then measure the ratio between the two by dividing the RT3 into the Free T3. The body produces the benign RT3 naturally to rid itself of excess of T4, but in some cases, such as high or low cortisol, RT3 is produced in excess which can clog cell receptors from receiving T3. FT3 is usually twenty or more times higher than RT3.

NOTE: If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests.
