Hi guys I have just got my results back and as indicated my tsh is too low, B12 levels are now higher thankfully and my antibodies are increased. Can anyone explain the two antibodies to me? I had the peroxides antibody test at my gp and this has come down significantly but I am concerned at how high the other antibodies are. What does this mean?? As in what's the difference between the two?? Also I'm vitamin D deficient so do I just take a daily vitamin D tablet? Is it that simple? Thanks guys for taking the time to look at this for me.
