MMA

Description

"Methylmalonic Acid" (MMA) test checks for elevated MMA levels, which may signal vitamin B12 deficiency or problems with nutrient absorption. It’s especially useful when symptoms like fatigue, memory issues, or nerve tingling suggest B12-related concerns. A blood or urine sample is tested to assess metabolic function. High MMA levels indicate the body isn’t processing B12 properly. Results help confirm diagnosis and guide treatment with supplements, dietary changes, or follow-up tests to restore neurological and metabolic balance.

Test Group Description

Metabolite Group: These tests focus on evaluating specific metabolites, offering insights into metabolic function and related health considerations.

Optimal Range

For All Individuals:

  • Conventional Unit: 0.00–300.00 nmol/L

  • SI Unit: 0.00–300.00 nmol/L

Normal Range

For All Individuals:

  • Conventional Unit: 0.00–378.00 nmol/L

  • SI Unit: 0.00–378.00 nmol/L

Results That Differ From The Norm (Direct and Indirect Causes)

Increased levels may indicate:


  • Celiac disease (Autoimmune disorder affecting the small intestine's ability to absorb nutrients)

  • Crohn's disease (Chronic inflammatory bowel disease affecting the digestive tract)

  • Gastric bypass surgery

  • Genetic factors (Inherited conditions affecting metabolism)

  • Imerslund-Gräsbeck syndrome (Rare genetic disorder causing v...

Key Reasons For Testing

  • Diagnosis of Vitamin B12 Deficiency: Detects elevated MMA levels indicative of impaired B12 metabolism.

  • Assessment of Pernicious Anemia: Aids in diagnosing anemia caused by B12 absorption issues.

  • Monitoring Response to Therapy: Tracks MMA levels to evaluate the effectiveness of B12 supplementation.

  • Differentiation of Megaloblastic Anemia: Distinguishes B12 deficiency from other macrocytic anemia causes.

  • Assessment of Neurological Symptoms: Identifies elevated MMA levels linked to B12 deficiency-related neuropathy or cognitive issues.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
