CORGENIX MEDICAL CORPORATION 13534 Corgenix Anti-Phosphatidylserine IgG Semi-Quantitative Test Kit (192 Well)

INTENDED USE Detection and semi-quantitation of anti-phosphatidylserine antibodies in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders (anti-phospholipid syndrome). For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE ANTI-PHOSPHATIDYLSERINE TEST High serum levels of anti-phospholipid antibodies are frequently detected in patients with autoimmune (i.e., 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 TEST The test is an indirect ELISA. Diluted serum/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/plasma proteins by washing, antibodies specific for human IgG or IgM, labeled with horseradish peroxidase (HRP), are added forming complexes with the phosphatidylserine bound antibodies. Two enzyme-conjugated antibody solutions are provided, one specific for human IgG antibodies and one specific for human IgM 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 anti-phosphatidylserine (aPS) antibodies. Results are obtained by reading the O.D. of each well in a spectrophotometer. Calibrator sera are provided for both IgG and IgM antibody concentrations expressed in GPS or MPS units. Control and patient results are determined from the calibration curve. Refer to Package Insert.

INTENDED USE For the detection and semi-quantitation of anti-cardiolipin antibodies in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders (anti-phospholipid syndrome). For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE TEST Anti-phospholipid antibodies are auto antibodies that react with most negatively charged phospholipids, including cardiolipin (CL). Anti-cardiolipin (aCL) antibodies are frequently found in patients with systemic lupus erythematosus (SLE). Elevated levels of aCL antibodies have been reported to be significantly associated with the presence of both venous and arterial thrombosis, thrombocytopenia, and recurrent fetal loss. The term “anti-phospholipid syndrome” (APS) has been introduced to describe patients who present these clinical manifestations.PRINCIPLE OF THE TEST The test is an indirect ELISA. Diluted serum samples, calibrator sera, and controls are incubated in cardiolipin coated microwells, allowing aCL antibodies present in the samples to react with the immobilized antigen. After removal of unbound serum proteins by washing, antibodies specific for human IgG labeled with horseradish peroxidase (HRP) are added forming complexes with the cardiolipin bound antibodies. Following another wash step, the bound enzyme-antibody conjugate is assayed by the addition of tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) as the chromogenic substrate. Color develops in the wells at an intensity proportional to the serum concentration of aCL antibodies. Results are obtained by reading the O.D. of each well with a spectrophotometer. Calibrator sera are provided, with the IgG aCL concentrations expressed in GPL units. One GPL unit is equivalent to 1 μg/mL of an affinity purified standard IgG sample. Control and patient results are determined from the calibration curve. Refer to Package Insert.

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.

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.
