This test measures the level of B12 in the body. B12 is a vitamin that is required for the production of red blood cells and for DNA synthesis.
Many people consume sufficient B12 through a healthy diet that includes fish, shellfish, meat, poultry, and eggs. Some people do not take in sufficient B12 or do not absorb it properly.
