The methylmalonic acid (MMA) test measures the amount of a substance called methylmalonic acid (MMA) in blood. MMA is typically made in tiny amounts when you digest protein. Your body makes large amounts of MMA if you have a drop in the amount of vitamin B-12. MMA is excreted through your kidneys.
Your body needs B-12 to make red blood cells and to help your central nervous system work as it should. Low levels of B-12 can cause anemia. This is when your body does not make enough red blood cells.

This test is used to diagnose a mild and early shortage of vitamin B-12. A high level of MMA can mean that you have a low level of B-12. Vitamin B-12 deficiency is the most common cause of MMA production. When you have a low vitamin B12 level and/or have symptoms of B12 deficiency such as numbness, tingling in the hands or feet, trouble walking, swelling of body tissues, or yellowing of the skin or eyes; as part of newborn screening, your Health provider will suggest going for this test.
Please do not exercise prior to testing. It is best that your blood is taken in a rested state.
Note: Turn around times on results are an estimate and are not guaranteed. The lab may need additional time due to holidays, confirmation/repeat testing, etc. You can contact us to discuss when your results should be ready and we will contact the lab on your behalf immediately.
