Another listed cause of high vitamin B12 serum is functional (active) vitamin B12 deficiency.

Excerpt from Chris Kresser's article: What Everyone (Especially Vegetarians) Should Know About B12 Deficiency:

"...be aware that a high serum B12 does not necessarily rule out functional/active B12 deficiency. In fact, I have come to view a high serum B12 in the absence of supplementation as a potential red flag for active B12 deficiency."

Excerpt from The New England Journal Of Medicine - Spurious Elevations of Vitamin B12 with Pernicious Anemia:

"Within a 3-week period, two women, 46 and 48 years of age, presented with peripheral neuropathy and associated pancytopenia with macrocytic anemia. Clinical suspicion for pernicious anemia was high, but vitamin B12 levels were 1644 pg per milliliter (1228 pmol per liter) and 1321 pg per milliliter (975 pmol per liter), respectively (reference range, 246 to 1320 pg per milliliter [181 to 974 pmol per liter]).

On subsequent bone-marrow evaluation, specimens from both patients showed profound megaloblastic features. Additional findings on laboratory tests included elevated levels of homocysteine and methylmalonic acid combined with detection of intrinsic factor–blocking antibodies and antiparietal-cell antibodies, which further supported the diagnosis of pernicious anemia."

My blood test results indicated High B12, High RBC, Low RDW and High M Spike. I am kind of worried since my mom died of Multiple Myoloma.   Maybe I am freaking out because of that.

Kidney disease has those symptoms, not to freak you out, but my mother had the same problem. Please get yourself checked!
