I suffer from all symptoms of underactive thyroid gland for almost 6 years, but at that time I was diagnosed with inflammatory Arthritis and spent all that time focusing on treatment for that. But then couple of years ago I was diagnosed with tumour in my neck (non cancerous) that need operation. I stopped my methotrexate treatment for arthritis over 6 months ago which made me more aware of the thyroid symptoms because I have very bad brain fog that made my focus very low and feeling heavy in my head, nausea and dizziness. I checked NHS website for my symptoms and few weeks back I did Thyroid Stimulating Hormones, T4, T3, and Cortisol blood tests in a private hospital as my GP was not considering doing it.
The results were:
The Thyroid Stimulating Hormone (TSH) is elevated and the free T4 level is low. The cortisol level is on the low side.
TSH - 4.490. Ref Range: 0.270-4.200
Free T4 - 11.89 : 12.0 - 22.0
Free T3 - 4.2 : 3.1 - 6.8
Cortisol - 159. : 166-507 Morning
Thyroid antibodies- Negative
I took the results to my GP and she booked me to do full blood tests because the private hospital used different reference ranges than NHS and to my surprise the results came normal! She said she can't refer me to Endocrinologist because the results are normal!
I read that NHS is using different reference range and that most people go to private consultants.
I don't understand how GP make serious decision on just blood tests ?
Does anyone have experience like mine in regards to conflicting blood tests ?
