  • Reverse T3

    Reverse T3 (rT3) is an inactive form of the thyroid hormone T3 that is produced under stress or illness when the body converts T4 into rT3 instead of active T3. It is used to assess thyroid hormone conversion efficiency and may help identify non-thyroidal illness or functional hypothyroidism.

  • T3 Uptake

    T3 Uptake is a test that indirectly estimates the number of available binding sites on thyroid-binding proteins, primarily thyroid-binding globulin (TBG). It is used alongside total T4 to calculate the Free Thyroxine Index (FTI), helping to assess thyroid function and differentiate between thyroid and binding protein abnormalities.
