I have had my latest blood test results, they are:
TSH - 0.42 mlu/L - range 0.27 - 4.20
Free Triiodothyronine - 5.00 pmol/L - range 3.9 - 6.7
Free Thyroxine - 19.7 pmol/L - range 12.7 - 20.8
Anti-TPO - >1000 IU/mL - range <100
The other antibody test is normal but I didn't write this down!
Vitamin D - 42.5 nmol/L - insufficient
The anti-TPO has risen from 360 to over 1000 (they haven't given the exact number) in the last 6 months and my doctor has reluctantly prescribed 800 IU of vitamin D a day (reluctantly because he still thinks that my lack of vitamin D is due to my lifestyle and not getting enough sun!)
I think I have hashimotos and other people on here and elsewhere also think the same but if all the other blood tests are normal (assuming they are from above readings) how do I get the doctors to prove hashimotos one way or the other and treat me accordingly?
What other blood tests should I ask for to help prove there is something wrong and that it's not all in my head. Would a scan of my thyroid help to diagnose?
