Device description
INTENDED USEAn enzyme-linked immunoassay (ELISA) for the detection of IgG antibodies to complexes formed byoxidized low-density lipoprotein (oxLDL) with β2-glycoprotein I (β2GPI) in individuals with systemic lupuserythematosus (SLE) and lupus-like disorders (antiphospholipid syndrome). For In Vitro Diagnostic Use Only.SUMMARY AND EXPLANATION OF THE ASSAYThe antiphospholipid syndrome (APS) is one of the most common causes of acquired hypercoagulability(thrombophilia) It is frequently diagnosed in the context of a systemic autoimmune disorder such asSLE (secondary APS), however, it may also occur in the absence of an obvious underlying disease(primary APS). Oxidative stress and oxLDL formation are common in patients with SLE and APS suggesting an important relationship between lipid peroxidation and clotting activation (hypercoagulability). The presence of circulating IgG anti-oxLDL-β2GPI antibodies seem to be etiologically important. PRINCIPLE OF THE TESTThis test is an indirect ELISA detecting IgG anti-oxLDL-β2GPI antibodies. Diluted serum samples, calibrator(s), and controls are incubated in microwells coated with the oxLDL- β2GPI complex. After the removal of unbound serum proteins by washing, anti-human IgG antibodies, labeled with horseradish peroxidase (HRP), are added. Following another wash, 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 IgG anti-oxLDL-β2GPI antibody. Results are obtained by reading the OD of each well in a spectrophotometer. Calibrator sera are provided, with the IgG anti-oxLDL-β2GPI antibody concentration expressed in G Units. A log-log regression analysis is performed with calibrator values plotted against calibrator mean O.D.’s. Controls and patient results are determined from the calibration curve. Refer to product package insert.
A collection of reagents and other associated materials intended to be used for the qualitative and/or quantitative detection of antibodies to oxidized low density lipoprotein-B2-glycoprotein I (OxLDL-B2GPI) complex in a clinical specimen, using an enzyme immunoassay (EIA) method. It is used to aid in the diagnosis of antiphospholipid syndrome (APS) and as a marker for atherothrombotic risk in patients with systemic lupus erythematosus (SLE) and other autoimmune disorders.
