Vitamin B12 test: what it is for
Vitamin B12 is needed by your nerves and to make red blood cells. Your body cannot make it: it comes from food, almost only from animal foods. If you run short, symptoms come late, which is why it is worth measuring in your blood.
Why it is done
Your liver keeps a store that lasts years. That is why a deficiency builds slowly, and symptoms come late.
How the vitamin B12 test is done
It is a blood test, done at a Bianalisi lab without a prescription. You can add other tests to the same draw.
