The upper cut-oof level, for most labs, is around 5.5. Therefore, a TSH (thyroid stimulating hormone) level of 6.8 can be indicative of mild hyperthyroidism. This should be followed up by a doctor visit, and possibly further testing (usually a repeat TSH and then, if needed, a thryoid scan or thyroid ultrasound). I hope this answer is helpful to you.
