Elevated serum B12 is rare, and usually indicates a serious, potentially life-threatening disorder. Levels of B12 in the blood may be increased in myeloproliferative disorders, such as chronic myelogenous leukemia (cancer of the blood) or polycythemia vera (a disease characterized by an increased number and abnormal shape of red blood cells). Elevated B12 can also occur in liver disease such as hepatitis, when liver cells are broken down and release B12 into the blood.
Elevated levels of serum cobalamin may be sign of a serious disease like leukemia, polycythemia vera, and several liver diseases like acute hepatitis, cirrhosis, hepatocellular carcinoma and metastatic liver disease. You should consult your doctor as soon as possible.
