I tested negative for GPCA, but I haven't done IFAB.
Having done GPCA, is that enough?
Should I also do IFAB? I am on eod si injections, but for my peace of mind and for my GP to stop upsetting me/scaring me with their lack of b12 knowledge. I'd really like to at least TRY for a confirmatory test.
Should I do IFAB? And if so, how long after injecting, so that I don't get a false positive or something (if that's even a thing)...
I know that there are lots of reasons for b12 issues, and this is only one. But, I want to try everything, if it would be useful.
Thanks,
S

Parietal Cell Abs negative? That's a start! However, IFAb ought to be done, and probably best to do it immediately before your next B12 jab. However, if you're EOD, then that's not going to make much difference. So long as the lab running the test is aware, then they can make the call of whether or not it is worth testing the sample.
Perhaps it's time to ask what exactly makes you, or your GP, think you actually have PA? It's a confusing time. Good luck.
