Testing for unbound T 4 is more accurate than testing ...TSH secretion is also influenced by thyrotropin -releasing hormone (TRH), which is synthesized in the hypothalamus. The precise mechanisms regulating TRH synthesis and release are unclear, although negative feedback from thyroid hormones inhibits TRH synthesis. Most circulating T3 is produced outside the thyroid by monodeiodination of T4.An elevated percentage of IG has not been found to be clinically significant as a sole clinical predictor of disease.

The National Academy of Clinical Biochemistry released data indicated that more than 95% of normal individuals have a TSH level below 2.5 mlU/L. If Free T3 is too far below Free T4 in their respective ranges, we may suspect a T4-T3 conversion problem, excess T4 converting to Reverse T3, or illness lowering the metabolic set-point. If Free T4 is high in reference range, if it's keeping TSH too low, less of that T4 will become T3 in the body. A low TSH can't nudge T4-T3 conversion ...Optimal TSH Levels.
