14928-6Triiodothyronine (T3) Free [Moles/volume] in Serum or PlasmaActive
Part Description
LP29126-7 Triiodothyronine.free
Free T3 (free triiodothyronine) is a measure of free circulating T3, excluding that which is bound to carrier proteins. This provides a more accurate measure of T3 levels because the carrier proteins can increase or decrease in various conditions artificially inflating or shrinking the total T3. T3 is discriminating for diagnosing and/or following the treatment of hyperthyroidism. It is not very useful at the low range of concentrations, so is not very helpful in diagnosing hypothyroidism. The thyroid delivers 20 times more T4 than T3, so T4 is the more relevant analyte except in special cases.
