About this test

Worried about a vitamin B12 deficiency? This test measures methylmalonic acid (MMA), which builds up in the blood when B12 levels are too low. It's more sensitive than a standard B12 test, making it useful if you have symptoms like fatigue, tingling in the hands and feet, or brain fog but normal or borderline B12 levels. This test helps assess whether your body is properly using B12 for energy and nerve function.
