Normal value ranges for vitamin B12 vary slightly among different laboratories and can range anywhere between 200 to 900 pg/mL. The general consensus is values less than 200 pg/mL constitute a B12 deficiency.
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.
