Hello there. I have just had the result of my IFA test and was hoping someone could help with interpretation. It was 1.69 (>6). According to the text that came with it, this clearly shows that I do not have PA. I have though read on this site that a negative result does not necessarily rule out PA. Since I assume this depends on how low or high the actual figure is can anyone tell me if this result definitely rules out PA or not? If not, what is the next step? I have all the usual symptoms of B12 deficiciency but am now thinking in terms of low stomach acid as a cause. Many thanks!
