| Methylmalonic Acid (MMA) Test : What is a methylmalonic acid (MMA) test? This test measures the amount of methylmalonic acid (MMA) in your blood or urine. MMA is a substance made in small amounts when you digest protein. MMA is needed for metabolism, which is the process that your body uses to change food into energy. Vitamin B12 plays an important role in metabolism. Part of this role is breaking down MMA into substances that help with metabolism. If your body doesn't have enough vitamin B12, it will continue to make more MMA than is broken down. High MMA levels can be a sign of a vitamin B12 deficiency. Vitamin B12 deficiency can happen if you are not eating enough B12 in your diet or if your body has difficulty absorbing it. Your body cannot make vitamin B12 on its own, so you have to get it from the foods you eat. This vitamin is found in foods such as: - Seafood such as fish, clams, and oysters - Dairy products - Chicken - Eggs - Meat Vitamin B12 is also found in some fortified foods, meaning the food has vitamins added to it. It's also available as a supplement. Vitamin B12 also helps to make red blood cells. A deficiency can lead to health issues, including anemia. This is a condition in which your blood has a lower-than-normal amount of red blood cells. Other names: MMA | |
