• No fasting is required for this blood test. You may eat and drink normally unless advised otherwise.
• Inform the laboratory team about any medications you are taking, especially blood thinners, anticoagulants, or immunosuppressive drugs.
• Share your medical history, including previous blood clots, miscarriages, or autoimmune conditions.
• Avoid strenuous physical activity immediately before the test.
• Carry your doctor’s prescription and valid ID proof at the time of sample collection.
• If repeat testing is advised, maintain similar conditions to ensure consistency in results.

The Anti-Cardiolipin Antibodies IgG test measures the presence of IgG antibodies that target cardiolipin. These antibodies can interfere with normal blood clotting mechanisms and are commonly associated with antiphospholipid syndrome (APS). This autoimmune condition increases the risk of thrombosis (blood clots) and pregnancy complications.

Doctors commonly recommend this test to:

• Investigate unexplained blood clots in arteries or veins
• Evaluate recurrent miscarriages or pregnancy complications
• Diagnose or monitor antiphospholipid syndrome
• Assess autoimmune conditions such as systemic lupus erythematosus (SLE)
• Support evaluation of abnormal clotting profiles

The test involves collecting a small blood sample from a vein in the arm. The procedure is quick, safe, and minimally uncomfortable. Results are interpreted alongside other related tests, such as Anti-Cardiolipin IgM, lupus anticoagulant, and additional antiphospholipid antibody panels.

A positive result indicates the presence of IgG antibodies, which may increase the risk of clot formation. However, a single positive result is not sufficient for diagnosis. Repeat testing after a few weeks is often recommended to confirm the persistence of antibodies.
