My Doctor sent me for tests (see results below) and which very helpful and knowledgeable Seaside Susie commented upon. Unfortunately the doctor did not ask for my Free Thyroxine to be tested so I had to get that done via Medichecks. My suspicion is that I am not converting very well.
Medichecks TSH 1.99 (0.27–4.2)
Free Thyroxine 20.3 (12.0-22.0)
Doctors FT3 (see below) = 3.9 (3.1-6.8)
I have stopped taking B12 as per advice from Seaside Susie and started with the other recommended vitamins.
I’m posting this whilst on holiday so I hope my iPhone cut and paste with previous results is working!
Thank you x
DOCTORS RESULTS
Serum free triiodothyronine level 3.9 pmol/L [3.1 - 6.8]

Above high reference limit
Refer to tinyurl.com/BiochemInfo for further
information about the investigation of hyperferritinaemia.
