Needs evaluation: If you are taking vitamin B12 then this is not a problem. If you aren't then I'm sorry to tell you that high B12 levels can be a sign of serious health problems including liver or kidney disease, myelproliferative disorders including leukemia and polycythemia vera and hypereosinophilic syndrome. It is important for you to be evaluated to find the underlying cause. See http://tinyurl.com/pvyna2z ...Read more

My vitamin B12 level was elevated on my lab results. The reference range shows to be 200-1100, and my result shows >2,000. What could cause this?
What might these lab results indicate, please?
Ferritin — 307, vitamin B12 — 257, mcv — 100.3, mch — 33.8, rbc count — 4.24, rbc size — 14.1
See a hematologist.: Ferritin is an indication of your iron stores. This level is elevated for your sex and age group. Causes can be many, most common acute hepatitis, infections, alcohol abuse. The MCV would go along with these same diagnoses although only very mildly elevated(cell size). The B12 level is also at the low end of normal which can happen from malnutrition and alcohol abuse and many other diseases. ...Read more
Vitamin B12 high at 1054 norm 221-700, all other vitamins dr checked were normal, should I be concerned? And I don't "suppliment" so why is this?
My vitamin B12 level 2 months ago was 450 pg/ml.it is now 250. I was taking 1500 mcg methylcobalmin/day orally. I stopped 10 days ago.is it normal?
No, unusual: It is rather unusual for B12 levels to drop while taking 1500 mcg methylcobalamin/day. This suggests you are not able to absorb B12, or at least that particular product. Supplements don't always really contain what is on the label & some have additives that reduce absorption. Consider trying methylcolbalamin from a reliable source; if it does not come up then you need B12 shots. ...Read more
