I’ve been on T3 for a couple of years and recently got restested by Medichecks. Results are surprising
Prior to starting T3, I had a FT3 result of 1.2 against a reference range of 3.1 - 6.8. FT4 fine and TSH slightly elevated. I felt dreadful.
A year on T3 and my FT3 result was 5.8 (same reference range). T4 and TSH low, but to be expected. Feeling much better.
Today, my FT3 is 25.7(!) which makes no sense whatsoever.
