About 3 months ago I went for my annual blood test for thyroid - my gp knows I'm taking NDT. My T3 came back as about 16 with a range of 3 - 6. Obviously this was too high so I was asked to reduce my NDT and come back in a couple of months for a repeat test. I was taking 3 grains per day. What I had forgotten was that I shouldn't have taken my NDT first thing in the morning before my blood test - duh!
Anyway I duly reduced my NDT by 1/4 tablet every 2 weeks until I was down to 2 and went back last week for another test. This time I didn't take my NDT before I went. Lo and behold my T3 is back down to what it was on Levo 0 3.9!
Now I know that it's better to be near the top of the range but now I don't know by how much to increase it to find a middle ground. I'm not due for another test for a year as my gp says it's fine although he did go on about my T4 being low (8.9 in a range of 11-26) and my TSH being <0.05 but I said my TSH was that on Levo anyway. I think they forget that I had half my thyroid removed 50 years ago so it's never going to work properly is it.
I felt great on 3 grains but I don't know how much the result of 16 was due to my having taken the tablets in the morning. Any thoughts gratefully received.
