My mum has been on levo for 20+ years, and like me never felt it made a difference. Due to my interaction with the forum I have been pushing her to get results and try and get T3 tested by doctor. She saw a new doctor who seemed sympathetic and listened to symptoms, agreed to order T3 and the lab ignored request I presume because TSH 'in range'.
TSH 3.99 (0.30 - 5.50)
Got mum to order medicheck kit and results as follows
THYROIDSTIMULATING HORMONE *11 mIU/L (0.27 - 4.20)
FREETHYROXINE 14.2 pmol/L (12.00 - 22.00)
FREE T3 3.66 pmol/L (3.10 - 6.80)
From earlier TSH I interpreted as she could try higher dose of T4 to get TSH under 1. This is confirmed by the low T4 and T3 results from medichecks. Convertion ratio looks about right though.
If doctor won't up levo, I have T3, would you suggest trailing a 1/4 25mcg with her T4.
The other issue is the TSH jumping.
The medichecks test was done early, but 2 days dose of T4 was skipped as she got up late 2 days earlier and I had said leave a full 24hrs clear and she didn't want to do the test late morning.
