I had recently had a thyroid test with medichecks, who I have used a lot in the past. Results are as follows
TSH - 0.5 (0.27 - 4.2)
T4 - 40 (12 - 22)
T3 - 6.5 (3.1 - 6.8)
I am on and off ptu and have been since 2013, right now I am on 50mg twice daily and feel generally quite well. My pulse is around 70bmp, bp is 78/122, regular periods, stable weight. Question is what would cause a high t4, but normal t3 and tsh and why do I feel well despite t4 being so high.
