Going for blood testss tomorrow. I have had Hashis for many years. I take 75 mg thyroxine. When I've asked for a copy of the tests in the past, all I've been given is one line of numbers. I know from here that I need much more. Please can someone tell me exactly what I need in my results. I know now that I shouldnt take thyroxine in the morning as usual before the test. This is a fasting test too.
