VITAMIN B-12

The vitamin B-12 test measures the level of vitamin B-12, an essential vitamin involved in red blood cell production, nerve function, and DNA synthesis, in the blood. This test is used to diagnose and monitor conditions affecting vitamin B-12 levels, such as vitamin B-12 deficiency, pernicious anemia, and malabsorption disorders. Low vitamin B-12 levels can indicate malnutrition, gastrointestinal disorders, or autoimmune diseases, while elevated levels suggest excessive supplementation. The vitamin B-12 test provides valuable information for assessing nutritional status, diagnosing underlying conditions, and guiding treatment decisions to manage vitamin B-12 levels effectively.
