Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

The National Institutes of Health recommends that the average man consume a mere 2.4 micrograms a day, which is actually the lowest daily recommended dose of any vitamin. “Vitamin B12 ...
Serum vitamin B 12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins. [1] Most of the time, 80–94% of vitamin B 12 in the blood binds to haptocorrin, while only 6–20% is binds to transcobalamin ll. [2] Only transcobalamin ll is "active" and can be used by the body. [1]

A diagnosis of vitamin B 12 deficiency is determined by blood levels lower than 200 or 250 picograms per ml (148 or 185 picomoles per liter). Measurement of blood methylmalonic acid (MMA), a vitamin B 12-associated metabolite, is a commonly used biomarker. [2] Deficiency is often suspected first, as diagnosis usually requires several tests.
Vitamin B 12 was discovered as a result of pernicious anemia, an autoimmune disorder in which the blood has a lower than normal number of red blood cells, due to a deficiency of vitamin B 12. [ 5 ] [ 16 ] The ability to absorb the vitamin declines with age, especially in people over 60.
Multivitamins nutrition facts label showing that the international unit of, for example, vitamins D and E correspond to different gram values. In pharmacology, the international unit (IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances.
