AMA (Anti-Mitochondrial) M2 At

At IntroLab in Belgrade, we are dedicated to delivering accurate and reliable tests crucial for our patients’ health. One important test we offer is the AMA (Anti-Mitochondrial) M2 At analysis, which is vital for identifying and monitoring certain autoimmune diseases. Our mission is to provide clear, precise information and the highest quality service.

What is AMA (Anti-Mitochondrial) M2 At?

AMA M2 At, or anti-mitochondrial antibodies type M2, are specific antibodies crucial in certain autoimmune diseases, such as primary biliary cirrhosis (PBC). These antibodies attack mitochondria, the cellular organelles responsible for energy production, causing significant cellular damage.

These antibodies are highly specific to mitochondrial enzymes, especially those involved in fatty acid metabolism. This can result in specific metabolic changes in patients with elevated levels of these antibodies. AMA M2 At can be detected in the blood years before any symptoms of the disease appear, making this test highly valuable for early diagnosis.

When is the test necessary?

The AMA M2 At test is usually recommended for individuals exhibiting symptoms of autoimmune diseases, including:

• Fatigue
• Itchy skin
• Jaundice
• Discomfort in the upper right abdomen

This test is also beneficial for those with a family history of autoimmune diseases.

Specifics and subtypes of the test

This test utilizes techniques like indirect immunofluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA). While these methods are specific and sensitive, they can occasionally yield false-positive or false-negative results. To confirm a diagnosis, repeating the test or conducting additional laboratory analyses may be necessary.

The AMA M2 At test is one type of anti-mitochondrial antibody test. There are several subtypes of AMA antibodies, including M1, M3, M4, M8, M9, and others. Each subtype has unique specificities and may be linked to different conditions.
