I went back to my GP today with the new guidelines from the PA Society. She said she'd never heard of them and anyway they follow the NICE guidelines. She did however agree to read them. I'd printed off the summary and the full article. So the BSH guidelines are not in NICE? What does NICE say about treatment?
She refused a therapeutic trial of B12 injections because my serum B12 is not low. She has sent me for a retest (now I've been off my supplements a few more weeks) and also for the Anti-Intrinsic Factor and Anti-Parietal Cell tests. I believe these may show if it's Autoimmune PA, but won't necessarily be accurate. They also wouldn't help diagnose a functional B12 problem. Does that sound right?
She did say she'd refer me to heamatology if I remain unconvinced so I suppose that is good thing, depending on who I see (based on other people's experiences) and they can authorize MMA and HoloT tests.
