{"product_id":"total-triiodothyronine-tt3","title":"Total Triiodothyronine (TT3)","description":"\u003cp\u003e\u003cspan\u003eThis assay is designed for the quantitative determination of total triiodothyronine (T3) in human serum and plasma. T3 is the active thyroid hormone responsible for regulating metabolism in target organs and is primarily formed outside the thyroid, especially in the liver, by converting thyroxine (T4) through 5'-deiodination. T3 levels in serum reflect peripheral tissue activity more than direct thyroid output. Reduced T3 levels, known as low T3 syndrome, can occur due to certain medications or severe non-thyroidal illnesses. Like T4, over 99% of T3 is protein-bound, but it has a higher receptor affinity despite lower binding protein affinity. Measuring T3 is valuable for diagnosing T3-hyperthyroidism, detecting early hyperthyroidism, and identifying thyrotoxicosis factitia.\u003c\/span\u003e\u003c\/p\u003e","brand":"Enlight","offers":[{"title":"24 TESTS","offer_id":52728687231275,"sku":null,"price":2736.0,"currency_code":"INR","in_stock":false},{"title":"48 TESTS","offer_id":52728687264043,"sku":null,"price":3600.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/1827\/3323\/files\/TT3-01.jpg?v=1772703196","url":"https:\/\/shop.encorebiomedicals.com\/products\/total-triiodothyronine-tt3","provider":"Encore Biomedicals ","version":"1.0","type":"link"}
