I am convinced that my boyfriend has problems absorbing B.12. He is showing some worrying signs of severe loss of memory and other symptoms. His B.12 blood tests are within the 'normal' range, which means according to our G.P. there isn't a problem. I want John to get a referral to a haematologist would this be the right route to go? Just don't know which way to turn, or would it be a good idea to get a private test, in which case who would do a B12 Intrinsic Test?
