ANTI CARDIOLIPIN PANEL

Anti-Cardiolipin Panel

What it is

The Anti-Cardiolipin Panel is a blood test that measures antibodies (IgG, IgM, and sometimes IgA) directed against cardiolipin, a phospholipid found in cell membranes. These antibodies are part of the antiphospholipid antibody group and are strongly linked to antiphospholipid syndrome (APS), an autoimmune disorder that increases the risk of abnormal blood clotting, pregnancy complications, and other vascular problems.

Uses

This test is primarily used to evaluate patients for antiphospholipid syndrome, especially those with unexplained blood clots, recurrent miscarriages, or other autoimmune conditions such as systemic lupus erythematosus (SLE). It may also help assess stroke, deep vein thrombosis (DVT), or pulmonary embolism when no other cause is identified. Doctors often order it along with lupus anticoagulant and anti-beta-2 glycoprotein I antibody tests.

Symptoms That May Lead to the Test

Doctors may recommend an Anti-Cardiolipin Panel if you have a history of recurrent miscarriages, unexplained blood clots, stroke at a young age, leg swelling, chest pain with shortness of breath, or autoimmune disease symptoms. It is also used in evaluating patients with suspected clotting disorders or unusual vascular events.

Abnormal Results

Positive Anti-Cardiolipin Antibodies: Suggests the presence of antiphospholipid antibodies, supporting a diagnosis of APS if persistent and accompanied by clinical symptoms. Higher levels may correlate with greater clotting risk or pregnancy complications.

Negative Anti-Cardiolipin Antibodies: Reduces the likelihood of APS, though repeat testing may be needed since antibodies can fluctuate over time.

Risks

The test involves a standard blood draw, with minimal risks such as slight pain, bruising, or temporary dizziness. There are no long-term risks associated with the procedure.
