About this test

Free Triiodothyronine (Free T3 or FT3) is the active form of thyroid hormone in our body - this is the actual hormone that does the work at the cellular level. Although not always needed for monitoring thyroid treatment regimes, many specialists advise testing the level of FT3 particularly if the treatment regime is less conventional.
