The Vitamin B12 test measures the level of vitamin B12 (cobalamin) in the blood, an essential nutrient required for red blood cell production, nerve function, and DNA synthesis. Adequate B12 levels are important for energy metabolism and neurological health.
This test is commonly used to evaluate vitamin B12 deficiency, which may cause anemia, fatigue, weakness, numbness or tingling, and cognitive changes. Vitamin B12 testing is often ordered alongside folate and homocysteine tests to help assess nutritional status and anemia-related conditions.
