Hi Everyone,
Im a bit out of my depth here and wondered if you could help please. Ive taken B Complex for nearly 25 years, I do wonder whether serum levels have always been scuppered, as I read again that to do a credible PA , MMA test I needed to be off B12 for minimum 4- 6 moths , possibly longer. And that even then this may be inconclusive or false. I have only managed to cease B12 supps for 5 weeks the effect was damaging.
Is this the same with the Gastric Parietal AB to be off B12 ? I note the NHS states positive Gastric Parietal AB should be treated with B12 injections to possibly arrest the antibodies regardless of PA being negative, and to not assume that PA neg is accurate.
Any thoughts would be greatly appreciated, every best wish . G
