B12 normal range: There is no harm in an elevated B12 level. The normal range is established based on a population study, but the physiology and diet factors that might lead to higher levels than those in the population study are not significant. Don't worry about it in the least. Get follow-up to see that the hemoglobin comes back to normal though.

Also treat iron deficiency and periodically let PCP MONITOR your iron as it can accumulate in body.
