What do the results mean?
If your results show higher than normal levels of MMA, it may mean you have a vitamin B12 deficiency. The test can't show how much of a deficiency you have or whether your condition is likely to get better or worse. To help make a diagnosis, your results may be compared with other tests including a homocysteine blood test and/or vitamin B tests.
Lower than normal levels of MMA are not common and not considered a health problem.
If you have questions about your results, talk to your health care provider.
If your baby has moderate or high levels of MMA, it may mean he or she has methylmalonic acidemia. Symptoms of the disorder can range from mild to severe and may include vomiting, dehydration, developmental delays, and intellectual disability. Left untreated, it can cause life-threatening complications. If your baby is diagnosed with this disorder, talk to your child's health care provider about treatment options.
