Methylmalonic Acid Blood Test

MMA Blood
Sample Report
Specimen Type: Blood


Methylmalonic Acid Blood Test

A Methylmalonic Acid (MMA) Blood test is most often used to aid in the diagnosis of Vitamin B12 deficiency. Methylmalonic Acid production is linked to the body's Vitamin B12 level. When B12 levels drop, more MMA is produced. An MMA test is one of the earliest indicators of Vitamin B12 deficiency.

Methylmalonic Acid testing is typically ordered when a person is suspected of having low Vitamin B12 levels due to symptoms or the results of previous testing. Because high MMA levels can sometimes be indicative of conditions other than B12 deficiency, a Homocysteine test can also be ordered for additional confirmation. MMA testing can also be done with a Methylmalonic Acid urine test for people who prefer a pain free, noninvasive specimen collection.  Urine testing may not be as accurate as a blood test in people who are experiencing kidney problems.

Turnaround time for the Methylmalonic Acid Blood test is typically 6-8 business days

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Incubation Period:

The Methylmalonic Acid Blood test has no fasting requirements.
