Best indicator of B12 deficiency

From Dr. Stratton: Homocystine levels are elevated with B12 and folatei deficiency, but can be reduced by folate alone. On the other hand, serum methyl malonate levels are elevated in B12 deficiency and are not changed by folate. Therefore, serum methyl malonate levels are the best indicator of B12 deficiency.

Thanks JimK for this
