I am on 30 mcg T3 and feel I am still under medicated so decided to have a blood test done to check my current levels. I have previously had blood tests done via the doctor and my thyroid antibody results were 385 IU/ml (less then 101) in Jan 2015 and 239 in March 2016. My recent test results from Medicheck are below and in the letter it said 'The antibody levels indicate there is no underlying autoimmune condition.' It also said 'Your thyroid hormone levels indicate that you definitely need T4 supplementation. Your T3 level is normal. Your vitamin D levels show that you have vitamin D insufficiency. This may progress to vitamin D deficiency if you don’t take steps to increase your vitamin D levels. Your B vitamins are normal.'
Can anyone help with these results please? Surely if I am on T3 only, then I shouldn't need T4 supplementation? They indicated that my T3 level is normal. Shouldn't it be higher? I don't understand the conflicting thyroid antibody results either.
