I am undiagnosed at the moment, but I am convinced there's something wrong with my B12 or iron. I have been anemic before due to iron defiency, twice. Anyway, the nurse gave me some of my blood test results the other day and both my B12 and Iron were within the "normal" range, but on the lower end. My B12 was 217 (the lowest value in the normal range was said to be 180) and my Iron was 30 (the lowest normal value said to be 20). Is this too low or not?
