  1. Beta-2-Glycoprotein I Antibody (IgA)

    Beta-2-Glycoprotein 1, apolipoprotein H, is a cofactor in antiphospholipid antibody binding and is the critical antigen in the antiphospholipid antibody syndrome. Beta-2-Glycoprotein 1 Antibody is more specific than …... More

  2. Beta-2-Glycoprotein I Antibody (IgG)

    Beta-2-Glycoprotein 1, apolipoprotein H, is a cofactor in antiphospholipid antibody binding and is the critical antigen in the antiphospholipid antibody syndrome. Beta-2-Glycoprotein 1 Antibody is more specific than …... More

  3. Thyroid, FNA Cytomorphology with Molecular Reflex

    This assay provides morphologic review along with appropriate molecular testing for diagnosis of thyroid samples obtained by fine needle aspirate (FNA). Any molecular testing required will be reflexed based on cytologic…... More

  4. Protein S Activity

    The congenital or acquired deficiency of Protein S increases the risk for thromboembolism, owing to a decrease of blood anticoagulant potential. It results in recurring thrombotic episodes. A decrease of Protein S leads…... More

  5. Protein C Activity

    Aids in diagnosis of decreased activity of Protein C characterized by recurrent venous thrombosis. Acquired deficiencies associated with Protein C include: Oral anticoagulant therapy, liver disease, vitamin K deficiency…... More

  6. JAK2 Exons 12 and 13 Mutations, Qualitative, Leumeta

    Myeloproliferative disorders (MPDs) are clonal hematopoietic stem cell malignancies characterized by excessive production of blood cells by hematopoietic precursors. In addition to thrombotic and hemorrhagic …... More

  7. C4 Binding Protein, Plasma

    C4B is a complement binding protein that specifically binds 50% circulating protein S, a vitamin K dependent cofactor of protein C activation. Since C4B may be elevated in certain disease states, this may affect the …... More

  8. Factor V (Leiden) Mutation Analysis

    Factor V (Leiden) Mutation is a point mutation that causes resistance of Factor V protein degradation by activated protein C (APC). This mutation is associated with increased risk of venous thrombosis.... More

  9. Factor V HR2 Allele DNA Mutation Analysis

    Factor V HR2 Allele, DNA Mutation Analysis is useful in patients who are carriers of Factor V Mutation (Leiden). Coinheritance of Factor V Mutation (Leiden) is associated with a 3-4-fold increased risk of venous …... More

  10. Factor VIII Activity, Chromogenic

    Preferred test in patients with Lupus anticoagulant, on heparin or direct thrombin inhibitors, or on Factor VIII concentrates.... More
