Order Free T3 Levels Test | Thyroid Testing (FT3)The Free T3 Levels Test measures the unbound portion of triiodothyronine, the thyroid hormone that acts on nearly every cell in the body. Because this fraction circulates freely rather than attached to carrier proteins, it offers a direct view of the hormone available to tissues.
About Free T3 Levels Test | Thyroid Testing (FT3) in Aberdeen
Triiodothyronine, commonly called T3, is one of the two principal hormones produced by the thyroid gland, the other being thyroxine, or T4.
Most T3 in the bloodstream is created when T4 is converted in peripheral tissues such as the liver and kidneys. Roughly 99 percent of circulating T3 is bound to proteins, leaving a small percentage as free T3, which is the biologically active form.
Because free T3 is not influenced by shifts in binding proteins, it can be a useful marker when total T3 results are difficult to interpret. Conditions that alter protein levels can distort total hormone measurements, while free hormone measurements remain comparatively stable.
Clinicians may order a Free T3 test alongside other thyroid studies to evaluate thyroid function, monitor known thyroid conditions, or investigate symptoms that suggest an imbalance. Results are typically interpreted together with thyroid-stimulating hormone, free T4, and clinical findings rather than in isolation.
