Quick answer
The Methylmalonic Acid Blood Test measures the amount of methylmalonic acid, or MMA, in the blood. MMA is a byproduct of normal metabolic processes that rises when vitamin B12 is insufficient. Because it can be more sensitive than a B12 measurement alone, it is often used when a deficiency is suspected despite a borderline B12 result. It is usually interpreted with other tests.
What this test measures
Vitamin B12 is needed for proper function of certain enzymes, and when it is lacking, methylmalonic acid accumulates in the blood. This makes MMA a functional marker of B12 status rather than a direct measure of the vitamin itself. It is frequently ordered together with vitamin B12, folate, and homocysteine to give a fuller picture of metabolism.
Kidney function influences MMA levels, because the kidneys help clear the compound. A provider may therefore consider creatinine and eGFR when interpreting results. Elevated MMA can also occur in some inherited metabolic conditions, which is why the result is evaluated in context rather than in isolation.
People may order this test when B12 deficiency is suspected, when a B12 result is borderline, or when symptoms such as fatigue or tingling raise concern. A qualified healthcare provider interprets the result with the person's diet, medications, kidney function, and other laboratory findings, and decides whether further testing is needed.
