i am 25 and just got blood work done, and my TSH was low, should i be concerned? I am worried i am not getting full potential gains, i have never taken T3 or T4, and i am about to get more tests done to check those, everything else i had checked had come back normal besides my liver values being a little high(avg is 35-60, and mine was 83, the doc wasnt concerned), i am getting a liver sonogram next week just to make sure my liver isnt damaged which it shouldnt be, but the low TSH concerns me, should i be?
