APL = IgA phospholipid units Some recent studies indicate that elevated levels of IgA class anticardiolipin antibodies are found in patients with systemic lupus erythematosus (SLE) and related disorders. In these studies, IgA values are higher in patients with vascular complications and thrombocytopenia. |
