A vitamin B12 level test measures the amount of B12 in your blood. B12 is an important vitamin for many basic bodily functions, such as brain health, blood cell production, and proper nerve functioning. Low B12 levels can lead to serious nerve damage and deteriorating brain functions.
Standard blood tests can detect B12 deficiency; however, the cutoff levels for deficiency (less than 200 pmol/L) may be inadequate, as some recent studies suggest a better cutoff may be possibly 300 to 350 pmol/L or higher.Some individuals with a low-normal B12 level in the blood can exhibit symptoms of B12 deficiency.he best way to make a definitive diagnosis of B12 deficiency is with a thorough history and physical exam followed by a blood test that evaluates B12 and folate levels since symptoms of folate deficiency can be similar to those of B12 deficiency, according to Gottleib.
