I've been trying to search through the forum, because I have seen this previously discussed and cannot find my answer. My B12 without supplements was 1936 last year and 1783 this year. My doctor says she has no idea why it is so high.

Mrs. D: I remember you saying there is a test that I can request to see if there are absorption issues. What is that test?

I know it can be a sign of other illnesses, but since it's high year after year, I would think I would be showing other signs if it were something like that. All other tests were fine. My D level was 37.

Thanks so much!
