【Intended use】

Triiodothyronine (T3) Test Kit (Immunoflurescence) is mainly for the in vitro quantitative determination of Total triiodothyronine content in human serum.Triiodothyronine (T3) is a thyroid hormone that is directly synthesized and secreted by the thyroid and converted from peripheral Thyroxine (T4). Its secretion is regulated by a negative feedback mechanism involving thyroid-pituitary-hypothalamus. For healthy people, the concentration of Triiodothyronine (T3) in the blood is 1/50 of T4, and 99.7% of Triiodothyronine (T3) is combined with Thyroxine-Binding Globulin (TBG) and albumin Such as protein binding exists. Compared withTetraiodothyronine (T4), Triiodothyronine (T3) is quick-acting, and its physiological effect is also several times more than that of T4[1], [2].Thyroid dysfunction can  cause excessive or insufficient T3 secretion. In addition, because thyroid function is directly affected by Thyroid Stimulating Hormone (TSH), the dysfunction of the pituitary gland or hypothalamus will affect the secretion of Triiodothyronine (T3).concentration changes are more sensitive than T4 in certain thyroid diseases, and the blood T3 concentration is more conducive to the identification of hyperthyroidism. Under the conditions of strong thyroid stimulation, T3 levels can also be a good assessment of the body's thyroid hormone reserves [3]. However, when the changes of pregnant women, estrogen and androgens affect the level of TBG, the level of Triiodothyronine (T3) cannot reflect the actual status of the thyroid [4], [5] . At present, the commonly used detection methods in laboratories include enzyme-linked immunoassay, immunofluorescence, colloidal gold and chemiluminescence.
