WebMar 27, 2024 · Thyroxine in blood is more tightly bound to serum proteins than is T3, consequently the free T4 (FT4) bioavailable fraction is less than free T3 (0.02% versus 0.2%, FT4 versus FT3, respectively). WebT3 in the blood (99.7 percent) is bound to blood proteins, but only the unbound T3 is active. The free T3 test measures the tiny amount of circulating T3 that is unbound, active T3. In contrast to the measurement of total T3, the advantage to measuring free T3 is that this test is not affected by changes in the thyroid-binding blood proteins.
