Methylmalonic Acid, Quantitative- Serum

The Methylmalonic Acid (MMA) test is a blood test that detects the level of methylmalonic acid present in your bloodstream. This substance is produced as a by-product of metabolism.

Metabolism is a physiological process that involves the conversion of food into energy. However, an excess of methylmalonic acid can impact your health negatively.

Vitamin B12 plays a key role in controlling the production of MMA. When you succumb to a vitamin deficiency, your body starts producing MMA in excess. This excessive production of MMA is detected by Apollo 24|7’s

Methylmalonic Acid test (MMA). The test can determine whether you have a vitamin B12 deficiency by measuring the levels of MMA in your bloodstream.

A vitamin B12 deficiency can be quite harmful. Characterised by symptoms like severe weakness and nerve problems, you must ensure that you consume enough of the vitamin. Since the human body does not manufacture it, you can consume it via food.

Following are some foods that are rich in vitamin B12:

• Cheese 
• Eggs
• Meat
• Fist 
• Certain breakfast cereals
• Beef
• Low-fat milk, etc.

A lower than average level of vitamin B12 in your bloodstream can cause various problems. If your body doesn’t receive enough of this important vitamin, you may start experiencing the following symptoms:

• Light headaches 
• Weakness
• Heart palpitations 
• Constipation
• Diarrhoea
• Tingling in the hands and feet 
• Confusion 
• Pale skin 
• Shortness of breath
• Nerve problems (muscle weakness, tingling, numbness, walking issues, etc.)
• Behavioural changes and other mental problems (depression, memory loss, etc.)
• Smooth tongue 
• Heart palpitations

In rare cases, a deficiency of vitamin B12 can also lead to a serious health disorder known as anaemia. This condition occurs due to a lack of red blood cells (RBCs) in the bloodstream.

Along with detecting a vitamin B12 deficiency, the test can diagnose a genetic disorder known as Methylmalonic Acidemia. This condition can have the following symptoms:

• Dehydration
• Vomiting 
• Intellectual disability
• Developmental delays 
• Here are some other commonly known causes of a vitamin B12 deficiency:
• Pernicious anaemia
• Gastritis 
• Digestive diseases (e.g., Crohn’s disease)
• Transcobalamin II deficiency
• Alcohol use disorder
• Surgery

Hence, if any of these conditions apply to you, it’s important to get the Methylmalonic Acid test done. The MMA test cost is affordable, and you can receive the test results within seven days.
