aCL Antibody – Normal, High, Low

aCL Antibody is used to help investigate inappropriate blood clot formation and to determine the cause of recurrent miscarriage. In addition, it can be used as part of an evaluation for antiphospholipid syndrome or sometimes other autoimmune diseases.

A blood sample may be required to be drawn from a vein in your arm. Normally, the antibodies are absent. They are detected in case of an infection.

A negative result means only that cardiolipin antibodies are not present or not present at a detectable level in the blood at the time of the test.

The low to moderate amounts of antibody  are frequently not significant, but they must be evaluated in conjunction with any signs, symptoms, and/or other clinical information.

Moderate to high levels of cardiolipin antibodies that persist when tested again 12 weeks later may be associated with an increased risk of excessive clotting or recurrent miscarriages.
