Hi there to our Redhedaussie friend! Cheers! and thanks for the post!
Having had blood tests fasting and others non-fasting, I can safely say that my levels go up in the fasting ones. It can look a bit scary to see a higher than usual TSH! I wouldn't put too much emphasise on it. The next test you get done will more than likely show a lowered TSH.
Cheers!
I don't think it would affect it any.
It was only one miss, very small amt for the body to tell the difference.
