Anti-Cardiolipin Antibody IgM+IgG

The Anti-Cardiolipin Antibody IgM+IgG is a blood test that helps to detect the presence of specific antibodies, immunoglobulin M (IgM) and immunoglobulin G (IgG), that target cardiolipins (lipid molecules normally found in cell membranes and platelets). This test helps diagnose autoimmune disorders like antiphospholipid syndrome (APS), which can increase the risk of blood clots.

The Anti-Cardiolipin Antibody IgM+IgG test detects antibodies that mistakenly target cardiolipin. These antibodies can indicate the presence of autoimmune disorders such as Antiphospholipid syndrome (APS), systemic lupus erythematosus (SLE) , and other conditions that lead to abnormal blood clotting. These antibodies may also be seen temporarily in individuals with acute infections, human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) , certain cancers or due to medications (such as phenytoin, penicillin etc.), or asymptomatically in the elderly.

The Anti-Cardiolipin Antibody IgM+IgG test measures both immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies that help determine the cause of an unexplained thrombotic episode(blood clots), thrombocytopenia (low platelet count),recurrent miscarriage(especially in the second and third trimesters of pregnancy), and with premature labor and pre-eclampsia(pregnancy complicated characterized by high blood pressure). Consider getting tested if you have symptoms suggestive of a thrombotic episode, such as pain and swelling in the extremities, shortness of breath, or headaches. This test can also be done in conjunction with lupus anticoagulant testing as a follow-up to a prolonged clotting time test  (Activated partial thromboplastin time, or APTT test).

If cardiolipin antibodies (IgM and IgG)  are detected initially, the Anti-Cardiolipin Antibody IgM+IgG test  is usually repeated 12 weeks later to help determine whether their presence is persistent or temporary. If an individual with a known autoimmune disorder tests negative for cardiolipin antibodies, they may be retested later as these antibodies may develop at any time in the future. Elevated levels of these antibodies can increase the risk of blood clots, which can lead to complications like Deep vein thrombosis (DVT), stroke etc. Low to moderate levels of cardiolipin antibodies are often of no clinical significance. The levels of these antibodies may fluctuate considerably over time, and this needs to be taken into account when testing.

No special preparation is required for this test However, inform your doctor about any medications or supplements that you are taking, as these may affect the test results. 

Lab test results may vary across laboratories. Do not try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results.The insights from this test helps the doctor tailor appropriate treatment plans to mitigate the risk of clotting and its associated complications.
