However, only the free (unbound) portion of T3 is responsible for the biological action. Further, the concentrations of the carrier proteins are altered in many clinical conditions, such as pregnancy. In normal thyroid function as the concentrations of the carrier proteins alters, the total T3 level changes so that the free T3 concentration remains constant. Thus, measurements of free T3 concentrations correlate more reliably with clinical status than total T3 levels. The increase in total T3 levels associated with pregnancy, oral contraceptives and estrogen therapy result in higher total T3 levels while the free T3 concentration remains basically unchanged.\u003c\/p\u003e","brand":"Abbkine Scientific Co., Ltd.","offers":[{"title":"48 T","offer_id":53338663551341,"sku":"KTE0004-48T","price":189.0,"currency_code":"USD","in_stock":true},{"title":"96 T","offer_id":53338911506797,"sku":"KTE0004-96T","price":289.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/KET0004.png?v=1778954844","url":"https:\/\/www.ebiohippo.com\/products\/elikine-free-triiodothyronine-ft3-elisa-kit-bhe13710210","provider":"BioHippo","version":"1.0","type":"link"}
