Bound hormones
WebTotal serum T4 is a measure of bound and free hormone. Changes in levels of thyroid hormone–binding serum proteins produce corresponding changes in total T4, even though levels of physiologically active free T4 are unchanged. Thus, a patient may be physiologically normal but have an abnormal total serum T4 level. WebTBG is the major thyroid hormone-binding protein in serum since it binds approximately two-thirds to three-fourths of T 4 and T 3. Both inherited and acquired variations of the …
