I'm looking for a good technical guide on diagnosing and managing B12 deficiency to give my GP. I want him to be better informed on managing my case which is complicated by high levels of methylmalonic acid.
The PASOC guides are not technical enough for this particular purpose. The best I found is this article. Is there anything else like it I could use, perhaps published in the last couple of years?
