your tsh result indicates you still have an underactive thyroid gland despite taking extra thyroid hormone (synthroid). the healthcare provider probably will be in touch with you to adjust your medication dosage. in the meantime you shouldn't do anything. you should never adjust your medications on your own. if you don't hear from the doctor who ordered your recent blood test be sure to call to make a follow-up appointment. the "reference range" for normal tsh values has been the subject of debate in recent years but a tsh level over 6. 0 clearly is high. this indicates the combination of thyroid pills plus the amount of thyroid hormone produced by your own thyroid gland still is low. don't worry. it can take quite some time to fine-tune the dosage of thyroid medication. and while a sluggish thyroid can be a nuisance it's not likely to have any life-threatening effects. wishing you well!
