INTENDED USEFor the detection and semi-quantitation of IgA anti-β2GPl antibodies in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders (anti-phospholipid syndrome). 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. Following another wash 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-β2GPl antibodies. Results are obtained by reading the O.D. of each well in a spectrophotometer. Calibrator sera are provided, with the IgA anti-β2GPl antibody concentrations expressed in A units. Controls and patient results are determined from the calibration curve.

INTENDED USEAn enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of Free Protein S Antigen in citrated human plasma. For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE PROTEIN S TESTProtein S is a vitamin K-dependent protein synthesized in the liver, vascular endothelium, and megakaryocytes, which plays an important physiologic role in the Protein C Anticoagulant System. This anticoagulant system is one of the major regulators of hemostasis by inhibiting clot formation and by promoting fibrinolysis. Protein S functions as a cofactor for activated Protein C on the vascular membrane to facilitate the degradation of clotting factors Va and VIIIa, down-regulating clot formation. In normal plasma approximately 40% of Protein S circulates as a free molecule, while 60% is complexed with C4b, a plasma protein of the classical complement pathway. Only Free Protein S is functionally active and able to bind to activated Protein C, while the complexed form of Protein S is not.Protein S deficiency, either congenital or acquired, may lead to serious thrombotic events such as thrombophlebitis, deep vein thrombosis, or pulmonary embolism. The prevalence of Protein S deficiency has been estimated to be less than 1 case per 300 in the general population. Two-thirds of patients with a congenital deficiency of Protein S (levels less than 50% of normal) may present with venous thrombosis in young adulthood. In young patients (<35 years) with a history of thrombosis, the prevalence may be as high as 15 to 18%. Acquired Protein S deficiency may be seen during pregnancy, oral contraceptive or oral anticoagulant therapy, liver disease, diabetes mellitus, postoperative complications, septicemia, and various inflammatory syndromes. A decreased Protein S activity in plasma may be the result of low concentrations or abnormal function of the Protein S molecule.Refer to Product Package Insert.

INTENDED USE The 11dhTxB2 Test Kit is an enzyme-linked immunoassay (ELISA) to determine levels of 11-Dehydro Thromboxane B2 (11dhTxB2) in human urine which aids in the qualitative detection of acetylsalicylic acid (ASA) effect in apparently healthy individuals post ingestion. For In Vitro Diagnostic Use.SUMMARY OF THE ASSAY Activated platelets produce Thromboxane A2 (TxA2), a potent vasoconstrictor and inducer of platelet aggregation. TxA2 is generated by Thromboxane synthase from molecules derived from arachidonic acid by cyclooxygenase-1 (COX-1). TxA2 has a short half-life in plasma and is rapidly hydrolyzed to Thromboxane B2 (TxB2). TxB2, in turn, is metabolized to 11-Dehydro Thromboxane B2 (11dhTxB2).The measurement of stable metabolites of TxA2, such as urinary11dhTxB2, is a means of quantitating TxA2 production in vivo and thus a direct way to analyze ASA’s effect post ingestion. PRINCIPLE OF THE TEST The 11dhTxB2 Test Kit measures urinary 11dhTxB2 and is performed as a competitive ELISA. Diluted samples (Reference Solution, controls, and patient urine), purified 11dhTxB2 conjugated to alkaline phosphatase (AP), and purified mouse monoclonal antibody directed to 11dhTxB2 are combined and incubated in microwells coated with a polyclonal anti-mouse antibody. The monoclonal antibody then binds to the polyclonal anti-mouse antibody coated on the microtiter plate. After the removal of unbound complexes by washing, the bound AP-11dhTxB2 conjugate is assayed by the addition of para-nitrophenylphosphate (pNPP) chromogenic substrate. Color develops in the wells at an intensity inversely proportional to the sample urine concentration of 11dhTxB2, and is read at 405nm. Results (pg/mL) are calculated against a reference curve prepared from the Reference Solution provided in the kit. Final results are reported as pg 11dhTxB2 per mg creatinine to normalize results for urine concentration. Refer to product package insert.

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.

INTENDED USE For the detection and semi-quantitation of IgG anti-prothrombin (aPT) antibodies in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders (e.g., antiphospholipid syndrome). For In Vitro Diagnostic Use.SUMMARY OF THE TEST Antiphospholipid antibodies are a heterogeneous group of immunoglobulins (IgG, IgM, IgA) that bind to several anionic phospholipids (e.g., cardiolipin, phosphatidylserine), to phospholipid-protein complexes, and to certain proteins in the absence of anionic phospholipids. The REAADS aPT ELISA test kit uses purified human prothrombin as antigen to detect IgG anti-prothrombin antibodies in human serum or citrated plasma in the absence of other exogenous cofactors or phospholipids. High serum or plasma levels of aPT antibodies may add valuable information in the laboratory assessment of antiphospholipid antibodies.PRINCIPLE OF THE TEST The test is an indirect ELISA. Diluted serum/citrated plasma samples, calibrators and controls are incubated in microwells coated with purified human prothrombin. After the removal of unbound proteins by washing, antibodies specific for human IgG labeled with horseradish peroxidase (HRP) are added forming complexes with the prothrombin bound antibodies. Following another washing step, the bound enzyme-antibody conjugate is assayed by the addition of a solution containing tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) as the chromogenic substrate. Color develops in the wells. Results are obtained by reading the O.D. of each test well in a spectrophotometer. Calibrator sera are provided with the IgG anti-prothrombin antibody concentration.

INTENDED USEAnti-dsDNA is an indirect solid phase enzyme immunoassay (ELISA) for the quantitative measurement of IgG classautoantibodies against double-stranded DNA in human serum or plasma. The assay is intended as an aid in the diagnosis of Systemic Lupus Erythematosus (SLE). For In Vitro Diagnostic Use.SUMMARY OF THE TESTAutoimmune diseases are characterized by the occurence of antibodies against one’s own antigenic structures, also known as autoantibodies. Presence of autoantibodies to native desoxyribonucleic acids (n-DNA, dsDNA, double-stranded DNA) is typical for the clinical picture of SLE. Antibodies against dsDNA belong to the group of Anti Nuclear Antibodies (ANA), which are directed against various structures of the nucleus of the cell. They appear in a variety of rheumatoid diseases. Antibodies to dsDNA are found during the active phases of SLE. Diagnostic sensitivity of the anti-dsDNA determination in cases of SLE is approximately 91 % combined with a diagnostic specificity of nearly 96 percent. SLE like diseases are caused by some drugs. For differential diagnosis of drug-induced SLE the determination of anti-dsDNA is a valuable diagnostic tool. PRINCIPLE OF THE TESTHuman recombinant double-stranded DNA (dsDNA) is bound to microwells. Antibodies to this antigen bind to the respective antigen. Washing of the microwells removes unspecific serum/plasma components. Horseradish peroxidase (HRP) conjugated anti-human IgG immunologically detects the bound patient antibodies forming a conjugate/antibody/antigen complex. Washing of the microwells removes unbound conjugate. An enzyme substrate in the presence of bound conjugate hydrolyzes to form a blue color. The addition of an acid stops the reaction forming a yellow color in the test well which is measured photometrically at 450 nm. The amount of color is directly proportional to the concentration of IgG antibodies present in the original sample. Refer to Product Package Insert.

INTENDED USEAn enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of Protein C Antigen in citrated human plasma. For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE TESTProtein C deficiency, either congenital or acquired, may lead to serious thrombotic events such as thrombophlebitis, deep vein thrombosis, or pulmonary embolism. Patients with a congenital heterozygous deficiency may present with venous thrombosis in young adulthood, while patients with the rare homozygous deficiency present with massive thrombosis (purpura fulminans) during the neonatal period. The prevalence of Protein C deficiency in the general population has been estimated at 1 in 300. In younger patients (<40-45 years) with recurrent venous thrombosis, the frequency of Protein C deficiencies may be as high as 10 to 15%. A decreased Protein C activity in plasma may be the result of low concentrations and function (type I) or only low function (type II).PRINCIPLE OF THE TESTThe Protein C Antigen assay is a sandwich ELISA. A capture antibody specific for human Protein C is coated to 96-microwell polystyrene plates. Diluted patient plasma is incubated in the wells, allowing any available Protein C to bind to the anti-human Protein C antibody on the microwell surface. The plates are washed to remove unbound proteins and other plasma molecules. Bound Protein C is quantitated using horseradish peroxidase (HRP) conjugated anti-human Protein C detection antibody. Following incubation, unbound conjugate is removed by washing. A chromogenic substrate of tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) is added to develop a colored reaction. The intensity of the color is measured in optical density (O.D.) units with a spectrophotometer at 450nm. Protein C Antigen relative percent concentrations in patient plasma are determined against a curve prepared from the reference plasma provided with the kit.Refer to Product Package Insert.

After removal of unbound serum proteins by washing, antibodies specific for human IgM 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 IgM aCL concentrations expressed in MPL units. One MPL unit is equivalent to 1 μg/mL of an affinity purified standard IgM sample. Control and patient results are determined from the calibration curve. Refer to Package Insert.

INTENDED USE An enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of Von Willebrand Factor Activity (VWF:Act) in citrated human plasma. For In Vitro Diagnostic Use.SUMMARY OF THE TEST Von Willebrand Factor Antigen (VWF:Ag or Factor VIII-related protein) is a plasma protein found in circulation combined by non-covalent interactions with Factor VIII (FVIII:C), a pro-coagulant protein also known as the anti-hemophilic factor. Deficiency of FVIII causes classic hemophilia while deficiency of VWF causes von Willebrand disease. Von Willebrand Disease is characterized by a deficiency or defect of VWF. Greater than 70% of Von Willebrand disease patients have a type 1 deficiency while approximately 20% have a type II deficiency. The laboratory diagnosis of Von Willebrand disease may require both quantitative and qualitative (functional) determinations to differentiate the two predominant subtypes of the disease, type I and type II. The classification of Von Willebrand disease into subtypes is important in determining the course of clinical treatment. PRINCIPLE OF THE TEST The REAADS VWF:Act assay is a sandwich ELISA. A monoclonal capture antibody specific for the portion of VWF which binds platelets is coated to 96-microwell polystyrene plates. Diluted patient plasma is incubated in the wells. The plates are washed to remove unbound proteins and other plasma molecules. Bound antigen is quantitated using horseradish peroxidase (HRP) conjugated anti-human VWF detection antibody. Following incubation, unbound conjugate is removed by washing. A chromogenic substrate of tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) is added to develop a colored reaction. The intensity of the color is measured in O.D. units with a spectrophotometer at 450 nm. Patient VWF:Act in relative percent concentration is determined against a curve made from the reference plasma provided with the kit. Refer to Product Package Insert.

INTENDED USEFor the detection and semi-quantitation of IgG anti-β2GPl antibodies in individuals with systemic lupuserythematosus (SLE) and lupus-like disorders (anti-phospholipid syndrome). 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 IgG 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 IgG, labeled with horseradish peroxidase (HRP), are added forming complexes with the β2GPl bound antibodies. Following another wash 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-β2GPl antibodies. Results are obtained by reading the O.D. of each well in a spectrophotometer. Calibrator sera are provided, with the IgG anti-β2GPl antibody concentrations expressed in G units. Controls and patient results are determined from the calibration curve.

For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE 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 TESTThe 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 IgM, 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 anti-phosphatidylserine (aPS) antibodies. Results are obtained by reading the Optical Density of each well in a spectrophotometer. Calibrator sera are provided with the IgM anti-phosphatidylserine antibody concentrations expressed in MPS (IgM aPS) units traceable to the reference preparations of the Louisville Antiphospholipid Laboratory Control and patient results are determined from the calibration curve.

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 IGA TEST Anti-phospholipid antibodies are autoantibodies 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.

INTENDED USEAn enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of Total and Free Protein S Antigen in citrated human plasma. For In Vitro Diagnostic Use.SUMMARY AND EXPLANATION OF THE PROTEIN S TESTProtein S is a vitamin K-dependent protein synthesized in the liver, vascular endothelium, and megakaryocytes, which plays an important physiologic role in the Protein C Anticoagulant System. This anticoagulant system is one of the major regulators of hemostasis by inhibiting clot formation and by promoting fibrinolysis. Protein S functions as a cofactor for activated Protein C on the vascular membrane to facilitate the degradation of clotting factors Va and VIIIa, downregulating clot formation. In normal plasma approximately 40% of Protein S circulates as a free molecule, while 60% is complexed with C4b, a plasma protein of the classical complement pathway. Only Free Protein S is functionally active and able to bind to activated Protein C, while the complexed form of Protein S is not.Protein S deficiency, either congenital or acquired, may lead to serious thrombotic events such as thrombophlebitis, deep vein thrombosis, or pulmonary embolism. The prevalence of Protein S deficiency has been estimated to be less than 1 case per 300 in the general population. Two-thirds of patients with a congenital deficiency of Protein S (levels less than 50% of normal) may present with venous thrombosis in young adulthood. In young patients (<35 years) with a history of thrombosis, the prevalence may be as high as 15 to 18%.7 Acquired Protein S deficiency may be seen during pregnancy, oral contraceptive or oral anticoagulant therapy, liver disease, diabetes mellitus, postoperative complications, septicemia and various inflammatory syndromes.8 A decreased Protein S activity in plasma may be the result of low concentrations or abnormal function of the Protein S molecule.Refer to Product Package Insert.
