(TSH) 4.56 μUI/mL ?

Very likely, if you were to have the FT4 and FT3 levels directly measured they would be in the normal range too. About 20% of people with normal TSH will have either a low FT4 or FT3. I would consider having them directly measured, but also look for other reasons for fatigue such as sleep, stimulant use, or anemia. ...Read moreSee 1 more doctor answer
