Target Details for Triiodothyronine T3

Target: Triiodothyronine T3 (T3)

Alternative Name: Triiodothyronine

Target Type: Amino Acid

Background: Optional[Gene Symbols]: Total triiodothyronine (TT3) represents the entire circulating pool of T3, encompassing both the protein-bound (~99.7 % ) and the biologically active free fraction (~0.3 %). Approximately 20 % of T3 is secreted directly by the thyroid gland, whereas 80 % arises from peripheral conversion of T4 in liver, muscle, kidney, and brain. Clinically, elevated TT3 may indicate hyperthyroidism, T3 toxicosis (elevated T3 with normal T4), or excessive thyroid hormone replacement. Conversely, reduced TT3 is observed in advanced hypothyroidism, severe systemic illness, starvation, chronic stress, and non-thyroidal illness syndrome (euthyroid sick syndrome).

The Total T3 Enzyme Immunoassay (EIA) Kit is a competitive immunoassay designed to quantify T3 in human, mouse, rat, porcine, feline, canine, equine, and sheep serum or plasma, as well as urine samples, within 3 hours. Absorbance is measured at 450 nm, and concentrations are interpolated from a ready-to-use T3 standard curve. The assay demonstrates a sensitivity of 0.167 ng/dL and has been validated for linearity, stability, precision, and spike-recovery performance. Each kit provides sufficient reagents to perform up to 96 assays, including standard curve and unknown samples.
