Abnormal TSH T4 Results

Hi everybody, I have been hypo for quite a number of years however my symptoms have vastly improved since embarking upon Chinese herbal therapy over the last 12 months or so. Today I had my latest test result from my western doctor who provided what I interpret as a contradiction (assuming UK lab tests use the same parameters as US labs when defining what is high, normal or low.

Can somebody please confirm for me that a T4 count of 16.5 is high.

My blood test received a feedback of T4 16.6 and TSH 7.3.

Correct me if I'm wrong but does that not appear to be a contradiction ?

I thought that normal T4 was somewhere between 0.7 - 2 give or take a small tolerance, and normal TSH was about 1 - 4.

My western doctor said that I should INCREASE the thyroxine from 100 mcg to 125 mcg.

So, what are the ranges/parameters that define high, normal or low T4 count ???

Appreciate any input.
