General Free Triiodothyronine (fT3) ELISA Kit

The Free Triiodothyronine (fT3) ELISA Kit from Assay Genie provides quantitative measurement of unbound T3 using a competitive immunoassay format. Triiodothyronine is the biologically active thyroid hormone that regulates metabolism, cardiac output, and protein synthesis, and its free fraction reflects the metabolically available hormone independent of carrier protein fluctuations. Researchers apply this assay to evaluate thyroid dysfunction, including hyperthyroidism and hypothyroidism, as well as in endocrinology investigations of the pituitary-thyroid axis. The kit uses a competitive binding principle, allowing accurate detection of free T3 in clinical and research laboratory workflows. Each package contains a pre-coated microplate, calibrated standards, detection reagents, and a complete protocol to support reproducible results. Store all reagents refrigerated to preserve antibody activity and standard stability; allow components to equilibrate to room temperature before running the assay.
