What is Methylmalonic Acid (MMA)?

Methylmalonic Acid (MMA) is a biomarker found in the urine and can assist in diagnosing Vitamin B12 deficiency. Vitamin B12 is crucial for the function of the nervous system and the production of red blood cells.

Why Test for MMA?

An MMA test can be useful if you have symptoms such as fatigue, weakness, constipation, loss of appetite, and tingling in the hands and feet. Testing for MMA is particularly helpful for the early detection of Vitamin B12 deficiency, even before the first symptoms occur.

What does it indicate?

An elevated level of MMA in the urine often indicates a Vitamin B12 deficiency. This is because Vitamin B12 is required for the breakdown of methylmalonic acid in the body.

What does a high MMA level mean?

A high level of MMA in the urine usually indicates a Vitamin B12 deficiency. This can lead to anemia, nerve damage, and other health issues if left untreated.

What does a low MMA level mean?

A low or normal MMA level in the urine suggests that sufficient Vitamin B12 is present in the body and that a deficiency is unlikely.

Frequently asked questions

Answers to what people usually want to know.

How does the home test work from A to Z?

After ordering we ship the collection kit to your home. You collect urine following the instructions, return it in the envelope, and receive your result digitally by email.

How do I collect my urine sample correctly?

Follow the included instructions, usually the midstream method in a sterile container. Pay attention to the right timing (first morning urine or random, depending on the test).

Do I need to avoid anything before collection?

For some tests yes (e.g. certain foods or supplements). Whether this applies is stated in the instructions. Read them before you start.
