Normal T3 and T4 but TSH level is down

Dear Ask The Doctor: I take thyroxine 200mcg per day now my current T3 and T4 level is normal but my TSH is 0.06uml please advise what can i do now

Dear Sadia: Your decreased TSH level may indicate a sub-clinical hyperthyroidism. You may need to consult your doctor to see whether the dosing of thyroxine needs to be altered.
