After taking advice here, I had a pin prick blood test via Blue Horizons, and these are the results: (I did the test quite late in the evening)
Ferritin 46.9 (Range 20 - 150 ug/L)
Free T4 10.28 (Range12 - 22 pmol/L)
Free T3 3.36 (Range 3.1 - 6.8 pmol/L)
TSH 4.13 (Range 0.27 - 4.20 IU/L)
Anti-Thyroidperoxidase abs 20.1 (Range <34 kIU/L)
Vitamin B12 146 (Range 142 - 725 pmol/L)
Would these results confirm a Hypothyroid state? What test, if any, should I look to do next?
Any and all suggestions gratefully received!
