Why Test for Anticardiolipin Antibody?

The Anticardiolipin Antibodies Test, or ACA Blood Test, aids in the diagnosis of antiphospholipid syndrome (APS). APS is an autoimmune disorder that produces anticardiolipin antibodies. These antibodies interfere with the blood clotting process, which can result in inappropriate or excessive clotting.

What does high anticardiolipin antibody mean?

Moderate to high levels of cardiolipin antibodies that persist when tested again 12 weeks later indicate the likely continued presence of that specific antibody, which may be associated with an increased risk of excessive clotting or recurrent miscarriages.

What does a positive Anticardiolipin IgM mean?

High levels of the IgM isotype are associated with autoimmune hemolytic anemia, a condition in which an individual's immune system attacks their red blood cells.
