Just checking my most resent blood tests. My t3 levels are 4.57 range 3-500. its the first time iv had t3 checked as usually they only test t4 and tsh. As my results are closer to the top end i was wondering how other people feel with this king of reading. Iv not been feeling well for some time and wondered if this could be the cause. My tsh is 0.81 range 0.34-5.60.
