Did you ever find the answer to your question? The reason I ask is because mine is also "out of range" (low rbc, high mcv and mch) but normal b-12 (lower end of the range) and extremely low iron storage. My doctors are unable to figure out why... I'm thinking pernicious anemia since my rbc is low in number but large in cell size (which suggests PA) but since my b12 is normal, and in combo with low iron storage (which is normally seen with low mch and mcv - smaller cell size) hey are ruling that out... Very frustrating.
