Device Description : INTENDED USEDetection and semi-quantitation of IgA anti-phosphatidylserine (aPS) INTENDED USEDetection and semi-quantitation of IgA anti-phosphatidylserine (aPS) antibodies as an aid for assessingthe risk of thrombosis in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders(anti-phospholipid syndrome). For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE TESTHigh serum levels of anti-phospholipid antibodies are frequently detected in patients with autoimmune (e.g., SLE) and non-autoimmune diseases, as well as in apparently healthy individuals. These antibodies have been associated with an increased risk for recurrent arterial and venous thrombotic events, thrombocytopenia, and fetal loss. Phosphatidylserine is a more physiologically relevant phospholipid due to its presence in cell membranes of endothelial cells and platelets.PRINCIPLE OF THE TESTThe test is an indirect ELISA. Diluted serum/citrated plasma samples, calibrator sera, and controls are incubated in phosphatidylserine coated microwells. β2-glycoprotein I is provided in the sample diluent. After the removal of unbound serum or plasma proteins by washing, antibodies specific for human IgA, labeled with horseradish peroxidase (HRP), are added forming complexes with the phosphatidylserine bound antibodies. Following another washing step, the bound enzyme-antibody conjugate is assayed by the addition of a single solution containing tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) as the chromogenic substrate. Color develops in the wells at an intensity proportional to the serum concentration of IgA Antiphosphatidylserine (aPS) antibodies. Results are obtained by reading the O.D. (optical density or absorbance) of each well in a spectrophotometer. IgA calibrator sera are provided, expressed as APS (IgA anti-phosphatidylserine) units. Control and patient results are determined from the calibration curve. Refer to Package Insert.

For In Vitro Use Only.SUMMARY OF THE TESTAnti-phospholipid antibodies are a heterogeneous group of immunoglobulins that bind to several anionic phospholipids, including cardiolipin and phosphatidylserine. High serum levels of anti-phospholipid antibodies are frequently detected in patients with autoimmune (e.g., SLE) and non-autoimmune diseases, as well as in apparently healthy individuals. Patients with positive reactions to both anti-phospholipid and anti-β2GPl assays were more likely to have clinical complications than those positive for only one. Higher prevalence and mean serum levels of IgA anti-β2GPl antibodies have been reported in autoimmune patients. In addition, anti-β2GPl antibodies in SLE patients correlated with clinical manifestations of anti-phospholipid syndrome.PRINCIPLE OF THE TESTThe test is an indirect ELISA. Diluted serum/plasma samples, calibrator sera, and controls are incubated in microwells coated with purified human β2GPl. After the removal of unbound serum or plasma proteins by washing, antibodies specific for human IgA, labeled with horseradish peroxidase (HRP), are added forming complexes with the β2GPl bound antibodies.
