the normal level of vitamin b12 in the blood is 200-1000ng/l. the levels of methylmalonic acid are generally high during anemia due to a lack of vitamin b12 or folic acid. methylmalonic acid can also be checked with a urine test. most hmos cover diagnostic services when medically necessary and prescribed by a participating physician. check with your insurance provider for more detailed information about your coverage.
