PRODUCT NAME: | AccuLite Free Thyroxine (fT4) |
INTENDED USE: | The quantitative determination of Free Thyroxine Concentration in human serum by a Microplate Chemiliuminescense Immunoassay (CLIA). |
PRODUCT OVERVIEW: | Thyroxine, the principal thyroid hormone, circulates in blood almost completely bound to carrier proteins. The main carrier is thyroxine binding globulin (TBG). However, only the free (unbound) portion of thyroxine is responsible for the biological action. Further, the concentration of the carrier proteins are altered in many clinical conditions, such as pregnancy but the free thyroxine concentration remains constant. Thus, measurements of free thyroxine concentrations correlate better with clinical status than total thyroxine levels. |
