Which blood tests? - results received

[Guest guest]

Hi & thanks to all who replied to my previous post " Which blood tests? " ,

We now have my wife's results:

Free T3 = 4.2

Free T4 = 18.7

TSH = 3.3

Comments (from NPTech):

TSH at the upper end of reference range (and inconsistent with free

thyroid hormone levels)

? Thyroid antibodies

My wife has been taking 50mg of thyrozine per day for about 5 years

and has also tested positive for autoimmune antibodies (by her GP).

Previous tests of T4 / TSH by GP are:

We would be very grateful for any comments / advice on the lab results.
