I've been given very little information on PA by my doctors and they have only just tested me for PA even though I have had borderline low b12 for over a year (I'm currently waiting for the results). I'm a 19 year old female and the doctors seem to be really reluctant to see whether I had PA or not and I don't understand why. I have a family history of coeliac disease and hypothyroidism for which I am negative for both, I even had an endoscopy for coeliac disease. So what else could possibly be causing my low b12? I have a very healthy diet with fish, diary and meat yet my GP says the most common cause of b12 deficiency for her is poor diet and its likely that I'm just someone who needs more b12 than others... Could that by right?
My other questions are:
-Do you have to be anaemic to have PA? I have never been anaemic.
-I have already had a test for gastric parietal cells and it was normal, could I still have PA?
-I was only ever borderline low around 148 (ref 150-1000) could it still be PA?
-I got tested for PA 2 hours after my first b12 injection, is it likely to disrupt the test? They are doing an IF test and the dr and specialist nurse seemed to say that it should be okay...
If you can answer just one of these questions it would be great
