Cardiolipin antibodies are the most common antiphospholipid antibody, a group of autoantibodies associated with excessive clotting and autoimmune diseases, such as lupus. They are frequently detected with other antiphospholipid antibodies, such as lupus anticoagulant and anti-beta-2 glycoprotein 1.

What is a normal Anticardiolipin level?
Reference range: IgG anticardiolipin: Weak positive: 15-40U/ml. Positive: >40U/ml.
What does positive anticardiolipin antibodies mean?
Anti-cardiolipin antibodies are by definition a major criterion for a diagnosis of APS. They are found in around 30-40% of patients with SLE. In both patients with primary and SLE associated APS positive results correlate with a predisposition for arterial or venous thrombosis, foetal loss, or thrombocytopoenia.
What causes cardiolipin antibodies?
Cardiolipin antibodies are autoantibodies produced by the immune system that mistakenly target the body’s own cardiolipins, substances found in the outermost layer of cells (cell membranes) and platelets. These autoantibodies can affect the body’s ability to regulate blood clotting in a way that is not well understood.
What does a positive anticardiolipin antibody mean?
The presence of an antiphospholipid antibody such as the lupus anticoagulant and anticardiolipin antibody in an individual is associated with a predisposition for blood clots. Blood clots can form anywhere in the body and can lead to stroke, gangrene, heart attack, and other serious complications.
What is Anticardiolipin blood test for?
Description. 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.

These antibodies interfere with the blood clotting process, which can result in inappropriate or excessive clotting.
What is cardiolipin IGG?
A cardiolipin antibodies test looks for a certain kind of antibody in your blood. … The levels of these antibodies are often high in people with abnormal blood clotting, autoimmune diseases like systemic lupus erythematosus (SLE), or repeated miscarriages.
What is anticardiolipin antibody positive?
1 The presence of anticardiolipin antibodies (especially those of moderate to high titer for IgG) is strongly associated with both arterial and venous thrombosis and recurrent pregnancy loss. 2-4 The IgM and IgA isotypes of anticardiolipin antibody have also been shown to be associated with venous thrombosis.
What causes antiphospholipid antibody syndrome?
Antiphospholipid syndrome (APS) is caused by the body’s immune system producing abnormal antibodies called antiphospholipid antibodies. This increases the risk of blood clots developing in the blood vessels, which can lead to serious health problems, such as: deep vein thrombosis (DVT) strokes.
Does anticardiolipin antibody go away?
The antibodies often fade away when the cancer is treated. The 2 most common types of antiphospholipid antibodies are lupus anticoagulant and anticardiolipin antibodies. Testing for lupus anticoagulant often uses a test such as the Russell viper venom time (RVVT) or kaolin clotting time.
What is the normal range for lupus anticoagulant?
The test results will show whether lupus anticoagulant antibodies are present in the blood. If your test shows they are, it should be repeated in several weeks to confirm. Normal values range from 20 to 39 GPL or MPL units.
What does a positive cardiolipin test mean?
Cardiolipin antibodies are the most common antiphospholipid antibody, a group of autoantibodies associated with excessive clotting and autoimmune diseases, such as lupus. They are frequently detected with other antiphospholipid antibodies, such as lupus anticoagulant and anti-beta-2 glycoprotein 1.
Can antiphospholipid antibodies go away?
People who have abnormal blood clots, repeated miscarriages, or autoimmune diseases such as systemic lupus erythematosus (SLE) and multiple sclerosis often have antiphospholipid antibodies. People with cancer may also have these antibodies. The antibodies often fade away when the cancer is treated.
Are you born with antiphospholipid syndrome?
At birth, infants of mothers with antiphospholipid syndrome may be small and underweight. A thrombosis or pregnancy complication is typically the first sign of antiphospholipid syndrome. This condition usually appears in early to mid-adulthood but can begin at any age.
What are the symptoms of lupus anticoagulant?
– swelling in your arm or leg.
– redness or discoloration in your arm or leg.
– breathing difficulties.
– pain or numbness in your arm or leg.
