ACA ELISA kits are assays designed to measure levels of ACA antibodies in biological samples, such as plasma, serum, culture extracts, and cell lysates. Anticardiolipin antibody (ACA) is a type of autoantibody reactive to cardiolipin, a component of the inner mitochondrial membrane. ACA is associated with systemic lupus erythematosus and other autoimmune diseases, as well as thrombosis, thrombocytopenia, and spontaneous abortion. ACA may also refer to adrenal cortex antibodies, which is associated with autoimmune Addison's disease. ACA ELISA kits are generally intended to detect immunoglobulins such as IgA, IgG, or IgM.
