Methylmalonic Acid, Serum

Methylmalonic Acid (MMA) testing is a powerful diagnostic tool, as elevated levels of MMA in the blood often indicate a Vitamin B12 deficiency. Since Vitamin B12 is crucial for metabolism and red blood cell formation, low levels can lead to symptoms like persistent fatigue, weakness, or nerve issues such as tingling in the hands and feet. This serum test measures the concentration of MMA, offering a highly sensitive way to determine if your body is properly utilizing or absorbing B12, even in early or mild cases. Identifying a deficiency early is key, as proper diagnosis and treatment can help prevent potential long-term nerve damage. Ask your provider about this test if you suspect low B12 or are experiencing related symptoms.
