t-3 free

– solid phase assay

this product is a solid phase competitive enzyme immunoassay. it is useful for the quantitative determination of free triiodothyronine (ft3) concentration in human serum.


l-triiodothyronine, a thyroid hormone, circulates in blood almost completely bound (>99.5%) to carrier proteins. the main transport protein is thyroxine-binding globulin (tbg). however, only the free (unbound) portion of triiodothyronine is believed to be responsible for the biological action. furthermore, the concentrations of the carrier proteins are altered in many clinical conditions, such as pregnancy. in individuals with normal thyroid function, as the concentrations of the carrier proteins change, the total t3 levels change in consert so that the free thriiodothyronine (ft3) concentration remains constant. thus, measurements of ft3 concentrations correlate more reliably with clinical status than total triiodothyronine levels.

for example, the increase in total triiodothyronine levels associated with pregnancy, oral contraceptives, and estrogen therapy result in higher total t3 levels while the ft3 concentration remains basically unchanged.

this microplate enzyme immunoassay methodology provides the technician with optimum sensitivity while requiring few technical manipulations in a direct determination of ft3.
