A Vitamin B12 test is a blood test that measures the concentration of Vitamin B12 in the bloodstream. Vitamin B12, also known as Cobalamin, is a crucial nutrient for maintaining healthy nerve cells, producing DNA, and forming red blood cells. It plays an essential role in brain function and the production of energy.
This test is commonly ordered when a person exhibits symptoms of Vitamin B12 deficiency, such as fatigue, weakness, numbness or tingling in the hands and feet, memory problems, or difficulty maintaining balance. A deficiency can lead to conditions like megaloblastic anemia and neurological issues.
The test is also used to monitor people with conditions that may affect Vitamin B12 absorption, such as pernicious anemia, gastrointestinal disorders (like Crohn’s disease or celiac disease), or following stomach surgery. Additionally, it may be used to assess dietary deficiencies, especially in individuals following strict vegetarian or vegan diets.
Blood samples are typically drawn from a vein, and the results help determine whether supplementation or treatment is necessary to restore healthy Vitamin B12 levels.
