Vitamin B12 Level Test
A vitamin B12 level test can measure how much vitamin B12 in your body. Based on the results, your doctor would determine whether abnormal levels of this nutrient are triggering problems. This procedure is recommended when you have a suspected deficiency of vitamin B12, pernicious anemia, high levels of serum folate, and early signs of leukemia, diabetes, or liver disease. A vitamin B12 level test can be a part of a blood test. Make sure to inform your doctor about any supplements and medications you take before the test starts. [7]
