TSH & T4 RESULTS

[Clarendon55]

My thyroxine medication was raised back in October from 75 to 100mg. I was then 2.98 miu/L, yesterday after blood test I was 0.24 miu/L. Have I been overmedicated do you think? (Incidentally, T4 level was 19.2). Appreciate any comments - thanks a lot!

How do you feel about

Was test done as recommended early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Do you always get same brand Levo at each prescription

Exactly what vitamin supplements are you taking

ALWAYS test TSH, Ft4 and Ft3 together

Also Testing vitamin D, folate, ferritin and B12 at least once a year
