Anti Phospholipid Antibody (APA) -IgG / IgM

Clinical definition of the Anti Phospholipid Antibody (APA) test
Antiphospholipid antibodies are autoantibodies associated with venous and arterial thrombosis; thrombocytopenia, and/or recurrent pregnancy loss. They prevent the blood to flow properly resulting in blood clots causing a health risk to both the mother and the baby. Some important types of phospholipid antibodies are: anticardiolipin; antinuclear and lupus antibodies.

Why is the Anti Phospholipid Antibody (APA) test done?
The antiphosolipid antibody test can check for elevated levels of all of the different types of antibodies. It can also be ordered to check on specific antibodies also. They play an important role in the body's ability to regulate blood clotting. It is used to determine the cause of recurrent miscarriage; evaluate or follow-up on a prolonged PTT (partial thromboplastin time) or as part of an evaluation for antiphospholipid antibody syndrome.

What are the common signs/symptoms when the Anti Phospholipid Antibody (APA) test is done?

  • Recurrent unexplained venous or arterial blood clots
  • Recurrent unexplained thrombotic episodes
  • Pain and swelling due to the thrombotic episodes
  • Shortness of breath
  • Migraine headaches
  • Deep vein thrombosis
  • Stroke
  • Heart attack
  • Recurrent miscarriages, especially in the 2nd and 3rd trimesters
  • Stillbirth
  • Placental insufficiency
  • Implantation failure
  • Increased rates of IVF failure

Who should do the Anti Phospholipid Antibody (APA) test (Target population)?

  • Patients suffering from the above symptoms due to inappropriate and unexplained blood clot formation
  • Pregnant females having  recurrent unexplained miscarriages especially in the 2nd and 3rd trimesters or unexplained infertility
