T3 Free Tracer Dialysis Test

The T3 Free, Tracer Dialysis Test quantifies both free T3 and total T3 to assess active thyroid hormone levels, especially in contexts of abnormal binding protein levels. Because it uses tracer dialysis, the assay reduces interference from thyroid hormone–binding proteins and offers enhanced accuracy in diagnosing hyperthyroidism, and distinguishing binding abnormalities from thyroid dysfunction.
