Methylmalonic Acid (MMA)


This blood test measures Methylmalonic Acid (MMA) levels. Methylmalonic acid is produced when certain amino acids break down in the body. Methylmalonic Acid is used to help detect early and/or mild vitamin B12 deficiency, especially at the tissue level.

Methylmalonic acid is an important component to evaluate when diagnosing vitamin B12 deficiency anemia. This test is frequently used in conjunction with a B 12 level and a homocysteine in order to have a more in depth look when assessing B12 and homocysteine levels. Methylmalonic acid levels may be elevated in those who suffer from kidney disease.

Test Preparation For Optimal Results:

If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
