Quick answer
The vitamin B12 test measures the amount of cobalamin in the blood. B12 is essential for normal nerve function and for producing healthy red blood cells. It is ordered when a deficiency is suspected because of diet, digestive conditions, or symptoms such as fatigue and tingling. The test uses a single blood sample, and a healthcare provider interprets the result with other findings.
What this test measures
Vitamin B12 is a water-soluble vitamin found naturally in animal foods, including meat, fish, eggs, and dairy. The body absorbs it with help from intrinsic factor, a protein made in the stomach, and stores a supply in the liver. Because of these stores, deficiency can take time to develop even when intake or absorption is poor.
The test measures serum cobalamin, and some laboratories add methylmalonic acid or homocysteine, which can become elevated when B12 is low. These secondary markers can be useful when the B12 result is borderline. A complete blood count may also be ordered to look for large red blood cells.
Risk factors for low B12 include a vegan diet without fortification, pernicious anemia, celiac disease, Crohn's disease, and some stomach or intestinal surgeries. Long-term use of certain medications can also reduce absorption. Testing helps a healthcare provider determine whether B12 is contributing to symptoms.
