Description: Methylmalonic Acid(MMA) is a substance produced when proteins (amino acids) in the body break down. MMA is used to help detect early and/or mild vitamin B12 deficiency, especially at the tissue level.

If an individual has kidney disease, he may have a high level of MMA in his blood. If the kidneys are not functioning properly, they cannot properly eliminate MMA in the urine, causing MMA to accumulate in the blood.
