Methylmalonate (MMA) – what do your levels mean?
Have you had your Methylmalonate (MMA) level measured and are unsure what the numbers mean? Here you will find a clear explanation of the normal range, what a high or low level might indicate, and when it makes sense to get tested.
What is the normal range for Methylmalonate (MMA)?
What is the normal range for Methylmalonate (MMA)?
The normal range for Methylmalonate (MMA) in the blood typically lies between 0.08 and 0.28 µmol/L. This interval can vary slightly depending on the laboratory and analysis method used. In elderly individuals, the level may be slightly higher, possibly due to reduced vitamin B12 absorption with age. If the values approach the upper limit, it could be a sign of incipient vitamin B12 deficiency or impaired kidney function. It is important to interpret the results in conjunction with the patient's symptoms and other blood tests, as elevated values can also be caused by other factors.
What does a low level mean?
A low level of Methylmalonate (MMA) is rarely clinically significant, as it usually indicates sufficient levels of vitamin B12 in the body. Symptoms of low MMA are therefore not typical, but it can be seen in individuals with a very high intake of vitamin B12, either through diet or supplements. There are no known health risks associated with low MMA, and it usually requires no treatment. If there is suspicion of underlying diseases, the doctor should assess the patient's overall health and other relevant blood tests.
What does a high level mean?
A high level of Methylmalonate (MMA) in the blood is often an indicator of vitamin B12 deficiency. Symptoms can include fatigue, dizziness, numbness, muscle weakness, and in severe cases, neurological problems such as balance issues and memory problems. The most common causes of elevated MMA are insufficient intake of vitamin B12, reduced absorption in the intestine, or impaired kidney function. Pregnant women and the elderly are particularly vulnerable groups. With elevated MMA, it is recommended to measure vitamin B12 levels and investigate for underlying causes such as pernicious anemia or intestinal problems. If the values are significantly elevated, one should consult a doctor for further investigation and treatment.
