What is a Methyl Malonic Acid (MMA) Test?
The MMA test, or Methylmalonic Acid Quantitative Test, measures the level of methylmalonic acid in your blood or urine. Methylmalonic acid is a substance your body produces in small amounts when it breaks down protein, and vitamin B12 plays a key role in processing it. When B12 levels are low, MMA builds up. The test is used to detect vitamin B12 deficiency and to identify certain rare metabolic disorders, particularly in newborns. It may also be called the MMA Serum or MMA Urine test, depending on the sample type used.
What Does a Methyl Malonic Acid (MMA) Test Measure?
The MMA test analyses the concentration of methylmalonic acid in the body. Here is what this measurement tells us:
| Component | What It Reflects |
|---|---|
| Methylmalonic acid (blood) | How well vitamin B12 is functioning in your body's metabolic processes |
| Methylmalonic acid (urine) | An early and sensitive sign of vitamin B12 deficiency; also used to monitor inherited metabolic conditions |
When vitamin B12 is adequate, MMA is converted into other substances used for energy production. If B12 is insufficient or a metabolic disorder is present, MMA accumulates to measurable levels in both blood and urine.
Why is a Methyl Malonic Acid (MMA) Test Done?
A doctor may order this test for several reasons, from investigating unexplained symptoms to monitoring a known condition.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to request an MMA test:
- Persistent fatigue or unexplained weakness
- Numbness or tingling in the hands and feet (paraesthesia)
- Difficulty with balance or coordination
- Memory problems, confusion, or difficulty concentrating
- Pallor (unusual paleness of skin)
- Nerve damage
- Mood swings
- Loss of appetite
- Irritability
Conditions This Test Can Help Detect
This test can help identify a range of conditions, including:
- Vitamin B12 deficiency
- Macrocytic anaemia (a condition where red blood cells are abnormally large)
- Chronic kidney disease (which can reduce the body's ability to clear MMA)
- Methylmalonic acidaemia (a group of rare inherited disorders seen in newborns where MMA builds up to harmful levels)
- Neurological complications such as peripheral neuropathy (nerve damage causing tingling or numbness) and ataxia (impaired coordination)
Methyl Malonic Acid (MMA) Test for Chronic Disease Monitoring
The MMA test is a useful tool for ongoing monitoring in certain conditions.
Raised urinary MMA is considered an early and sensitive marker of vitamin B12 deficiency, and the test can confirm whether B12 supplementation is working.
For patients with inherited metabolic disorders such as methylmalonic aciduria, periodic MMA measurement helps track disease management and treatment response. Your doctor will decide how frequently monitoring is needed based on your specific condition.
How to Prepare and What to Expect
Preparing correctly helps ensure your results are as accurate as possible.
Do You Need to Fast?
Yes, fasting is required for the MMA blood test. Avoid food and drink (except plain water) for 8 to 10 hours before sample collection. Always follow your doctor's or the laboratory's specific instructions, as requirements can vary.
Practical Tips Before Your Test
Keep the following in mind before your appointment:
- Tell your doctor about all medications and supplements you take. Antibiotics, metformin, proton pump inhibitors, and H2 blockers can all affect vitamin B12 absorption and MMA levels.
- Avoid excessive alcohol in the days before the test, as it can interfere with B12 absorption.
- If you have received a vitamin B12 injection within the past two weeks, let your doctor know, as this may affect your results.
- Drink plenty of plain water to stay well hydrated, which makes blood collection easier.
Step-by-Step Procedure
Here is what to expect during sample collection:
For blood sample:
- Arrive at the collection centre or greet the home collection professional at your scheduled time.
- The technician cleans the skin over a vein in your arm with an antiseptic and applies a tourniquet to make the vein more visible.
- A small needle is inserted, and a blood sample is collected into the appropriate tube. The process takes under a minute.
- The needle is removed, and gentle pressure is applied to the site to stop any minor bleeding.
For urine sample:
- For a urine sample, you will be given instructions to collect either a random urine sample or all urine produced over 24 hours at home.
- Your sample is labelled and dispatched to the laboratory for analysis.
Factors That Can Affect Accuracy
Several factors can influence your MMA test results:
- Impaired kidney function (the kidneys clear MMA, so kidney disease can raise levels independently of B12 status)
- Recent vitamin B12 injections or high-dose supplements
- Dehydration
- Intestinal bacterial overgrowth
- Impaired thyroid function
- Inherited methylmalonic aciduria
Understanding Your Methyl Malonic Acid (MMA) Test Results
Your results should always be reviewed alongside your symptoms and medical history. The table below shows generally accepted reference ranges, though these can vary between laboratories.
| Sample Type | Normal Range | Unit |
|---|---|---|
| Serum or Plasma MMA | Less than 0.40 | µmol/L |
| Serum or Plasma MMA (alternative unit) | Less than 370 | nmol/L |
| Urine MMA | 4.0 or less | mmol/mol creatinine |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how results are interpreted:
Impaired kidney function can raise MMA levels on its own, separate from any B12 deficiency, because the kidneys are responsible for clearing MMA from the body. Your doctor will consider your kidney function when reading your results.
MMA levels also tend to rise gradually from early adulthood onwards. This age-related increase is linked to a natural, gradual decline in both kidney function and vitamin B12 status over time.
How to Maintain Healthy Levels
The following general habits can support healthy MMA and B12 levels:
- Include B12-rich foods in your daily meals, such as meat, fish, eggs, and dairy products. Those following a vegan diet may benefit from B12-fortified foods or supplements after consulting a doctor.
- Address any digestive conditions that may reduce B12 absorption, such as atrophic gastritis or coeliac disease, with guidance from a healthcare professional.
- Keep up with routine health check-ups, especially if you are over 60 or follow a restrictive diet.

Frequently Asked Questions
The MMA test measures the level of methylmalonic acid in blood or urine. Doctors use it to check for vitamin B12 deficiency, investigate unexplained neurological symptoms or anaemia, and screen newborns for rare inherited metabolic disorders. It is also used to monitor patients already receiving B12 treatment.
When vitamin B12 levels start to fall, MMA can rise before standard B12 blood test results appear abnormal. This makes the Methylmalonic Acid Quantitative Test particularly useful when B12 levels are borderline or when a doctor suspects early or mild deficiency despite a seemingly normal result.
Yes, avoiding food and drink, except plain water, for 8 to 10 hours before collection. Always follow the specific instructions given at the time of booking, as requirements can vary.
Yes. Because the kidneys help clear MMA from the body, reduced kidney function can raise MMA levels on its own. Your doctor will take your kidney health into account when interpreting your MMA serum or MMA urine results.
A raised MMA alongside an apparently normal B12 level can still point to an early or mild B12 deficiency. Your doctor will look at your full picture, including symptoms and other test results, before drawing any conclusions.
Yes. In newborns, a small blood sample collected from the heel is used to screen for methylmalonic acidaemia, a rare inherited disorder where the body cannot properly break down MMA. Early detection allows for prompt management.
This test is commonly considered for people with symptoms of B12 deficiency, older adults, those following vegan or vegetarian diets, patients with digestive conditions that affect nutrient absorption, and individuals with unexplained anaemia or neurological complaints. Your doctor will advise if this test is right for you.
