About this test
Vitamin B12 is needed to make red blood cells and to maintain the sheath around your nerves. Deficiency is common in vegetarian diets, after certain stomach surgery, and with long-term use of some diabetes and acid-reducing medicines. Because the nerve damage can become permanent, it is worth checking early when there is unexplained tingling or numbness.
