The Vitamin B12, Serum Test measures the level of vitamin B12 in your bloodstream. This test is crucial for detecting vitamin B12 deficiencies, which can affect red blood cell production, nerve health, and brain function. Vitamin B12 is essential for DNA synthesis, and a deficiency can result in anemia, cognitive impairments, and neurological issues. This test is often prescribed if you experience symptoms such as fatigue, weakness, memory loss, or numbness. It is also commonly recommended for individuals who are at risk of B12 malabsorption, including those with digestive disorders or individuals following a vegetarian or vegan diet.

Low vitamin B12 levels detected by the Vitamin B12, Serum Test can signal a range of health risks, such as megaloblastic anemia, which causes red blood cells to become abnormally large and unable to carry sufficient oxygen. Left untreated, a B12 deficiency can also result in irreversible nerve damage, leading to numbness, tingling, and balance issues. High levels of vitamin B12, although rare, could indicate underlying conditions such as liver disease or diabetes. Regular monitoring of serum B12 levels helps manage these risks and ensures optimal health.
