Research in recent years has shown that biochemically euthyroid levels of thyrotropin (TSH) and serum free thyroxine (FT4) as determined by laboratories may not necessarily equate to clinical well-being of patients. The defined normal range of TSH and FT4 are wide and may differ from patients’ optimal range of TSH and FT4. We have previously described a deterministic mathematical model that can predict each patient’s unique homeostatic set point, which gives the opti...
