Autoantibody Testing

The body produces antibodies, one of the most important parts in the immune system, when it’s threatened by foreign substances. Then the antibodies react with certain cells to weaken the threat. Normally, the immune system works well.

 

But in some cases, the immune system cannot distinguish between “foreign substances” and the body’s own. That’s when the body produces autoantibodies to attack its own cells. And symptoms such as inflammation and dysfunction of organs occur. Autoantibody Test is thus used to help diagnose the condition.

 

Autoantibody Test varies. The most common one is the antinuclear antibody (ANA) test. Others include Antineutrophil Cytoplasmic Antibodies (ANCA) Test, Anticentromere Antibodies (ACA) Test, etc.

 

Usually, interpretations of the test should be drawn in the context of the person’s medical history and other information.
