Normal Results Return to top
Normal values are from 0.4 to 4.0 mIU/L for those with no symptoms of abnormal thyroid function. However, those without signs or symptoms of an underactive thyroid who have a TSH value over 2.0 mIU/L but normal T4 levels may develop hypothyroidism sometime in the future. This is called subclinical hypothyroidism (mildly underactive thyroid) or early-stage hypothyroidism. Anyone with a TSH value above this level should be followed very closely by a doctor.
If you are being treated for a thyroid disorder, your TSH level should be between 0.5 and 2.0 mIU/L.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
Knew that. THere's a strong indication that many more people have thyroid problems than the current standard of tests suggests. For years it was "only a small % of the population has it". Within the last few years it's been suggested that 1/3-1/2 of all obese folks have it and that our current testing misses them. (That's why I went in after much research requesting a litany of tests.) This is one of the reasons behind the statement I've made repeatedly about the importance of higher protein and low carb and that it's most efficacious in the obese population.
