When these hormones are present in the sample, they bind to the antibodies and produce a chemiluminescent reaction that emits light. The analyzer measures the intensity of the light produced, and the amount of light is proportional to the concentration of the hormone in the sample.

In circulation, only about 0.03% of T4 exists in its free, biologically active form, while the rest is bound to proteins such as thyroxine-binding globulin (TBG), pre-albumin, and albumin. Measuring free T4 provides a more accurate assessment of thyroid function, independent of fluctuations in binding proteins, making it useful in diagnosing thyroid disorders and monitoring thyrosuppressive therapy.

T4, the primary hormone secreted by the thyroid gland, plays a vital role in regulating metabolism and supporting cellular development. It is produced in the thyroid by coupling two DIT (3,5-diiodotyrosine) molecules and is stored bound to thyroglobulin, released under the control of thyroid-stimulating hormone (TSH). Over 99% of T4 in the blood is protein-bound, and variations in binding protein levels—due to factors like pregnancy or medications—can affect total T4 measurements. Therefore, binding protein status must be considered when assessing thyroid function.

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.

TSH is a glycoprotein hormone composed of two subunits, with the β-subunit providing TSH-specific immunological and biological activity, while the α-subunit is shared with LH, FSH, and hCG. It is produced by basophil cells in the anterior pituitary and follows a circadian secretion pattern. TSH plays a key regulatory role in thyroid hormone synthesis and secretion and also has a proliferative effect on thyroid cells. Because even minor changes in free thyroid hormone levels cause significant shifts in TSH levels, TSH measurement is a highly sensitive and specific tool for evaluating thyroid function. It is especially valuable for early detection or exclusion of dysfunctions in the regulatory axis between the hypothalamus, pituitary, and thyroid.\u003c\/span\u003e\u003c\/p\u003e","brand":"Enlight","offers":[{"title":"24 TESTS","offer_id":52728678482219,"sku":null,"price":2736.0,"currency_code":"INR","in_stock":true},{"title":"48 TESTS","offer_id":52728678514987,"sku":null,"price":5040.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/1827\/3323\/files\/TSH-02.jpg?v=1772703490"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/1827\/3323\/collections\/Thyroid.jpg?v=1772686371","url":"https:\/\/shop.encorebiomedicals.com\/collections\/thyroid.oembed","provider":"Encore Biomedicals ","version":"1.0","type":"link"}
