I am going to have a b12 intrinsic blood test by my own accord. Mainly because I feel awful and secondly I'm not convinced my results are normal.
Serum vitamin b12 level 336 187-883
Serum folate level 2.5 3.1-20.5
Serum ferritin level 45 20-204)
Any advice would be great. Is the b12 intrinsic test going to paint a better picture?
Thanks in advance.
Feeling pretty run down
