Sorry to be a pain folks, I've just noticed something in tiny writing on my blood test print out I got on Friday, that I don't understand.
I have found myself a good nutritionist that I am booked in to see next week but I wonder if anone on the site knows anything about IgA levels. I skimmed over my result, as I thought this was my coeliac test result and I'd been told that was normal and as it is at level 1 u/mL and guideline is < 10.00/mL on the printout, I read on BUT I've just read in tiny print underneath that, it says ' Please note: this is an IgA auto antibody test. False negatives occur in those with IgA deficiency.'
I'm probably being incredibly thick but I thought coeliac tests were pretty conclusive and if antibodies were present, a biopsy on the villi was done for confirmation of the disease. I don't understand how IgA deficiency is measured and if 1 is okay, then how does one know if it's a false negative?
That probably sounds as clear as mud but can some wiser soul than me, clarify this for me, please.
Thank you very much.
