Phosphatidylinositol Antibody (IgM)

The Phosphatidylinositol Antibody (IgM) test contains 1 test with 1 biomarker.

Phospholipid autoantibodies specific to phosphatidylinositol (PI), phosphatidylglycerol (PG), phosphatidylserine (PS), phosphatidylethanolamine (PE), phosphatidylcholine (PC), phosphatidic acid (PA), cardiolipin (CL) and sphingomyelin are found in hematologic autoimmune diseases, especially anti-phospholipid syndrome (APS) and systemic lupus erythematosus (SLE). APS is characterized by arterial and venous thrombosis, thrombocytopenia, and recurrent fetal loss; thrombosis, thrombocytopenia and hemolytic anemia also occur in SLE and are associated with the presence of phospholipid autoantibodies.
