A Vitamin B12 test measures the level of vitamin B12 in the blood. This essential vitamin plays a crucial role in red blood cell production, nerve function, and DNA synthesis. A deficiency can lead to symptoms like fatigue, weakness, memory problems, and anemia. The test helps diagnose B12 deficiency, which can result from poor diet, malabsorption, or medical conditions affecting the stomach or intestines. It may involve blood sampling and sometimes additional tests, like methylmalonic acid (MMA), to assess B12 activity in the body.
