Hi. I started 125 Levo 3 months ago and my Thyroid test results now seem optimal (results shown below). I have been taking Vit D, B12, Iron and a multi vitamin since my last GP blood test showed these could be improved. I would like to have my Ferritin, Vit D, B12 and Folate tested and will have to go privately. What medication/supplements should I stop before taking the test? Also, are you aware of the cheapest test where I could get all 4 tested together. Medichecks have these in all different tests so it will cost quite a bit to get them all done. Thanks
TSH 0.06 (0.2 to 4.5), T4 18 (9 to 21) and T3 1.7 (0.9 to 2.4).
