I was called in recently by my GP practice for a review of my thyroid hormone prescription. My usual GP has retired and I saw a doctor who said it was very unusual to be on T3 and she had not done a test for it before!
I asked her what she wanted me to do about taking my L-thyroxine and Liothyronine before the test as I have had different instructions from different doctors. She said to take my normal dose before the test which will be at 9.45am. I usually take it at about 7.15 - 7.30 am.
I am wondering what the correct procedure is?
