  1. 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

  2. Antithrombin III Activity

    Antithrombin III Activity CPT Code(s) 85300 Methodology Chromogenic Substrate Limitations Expected impact by therapeutic levels (potential interference depends upon drug concentration): Warfarin: no effect; Heparin (UFH…... More

  3. Antiphospholipid Syndrome Diagnostic Panel

    This assay may be useful in supporting or ruling out a diagnosis of antiphospholipid syndrome.... More

  4. Antithrombin III Antigen

    A decrease in Antithrombin III may predispose an individual to thrombosis and to failure to respond to heparin therapy. This can occur as a result of a congenital deficiency, secondary to liver transplant, DIC, …... More

  5. BCR-ABL1 Gene Rearrangement, Quantitative, PCR

    This reverse-transcription PCR-based assay detects the BCR-ABL1 transcript produced by the t(9;22) chromosomal translocation associated with chronic myelogenous leukemia (CML) and a subset of lymphoblastic leukemias. …... More

  6. Activated Protein C-Resistance

    Activated Protein C (APC) resistance is the most frequent hereditary defect associated with deep vein thrombosis. Over 95% of the APC resistance phenotype is due to the Factor V Leiden Mutation. The APC-resistance assay…... More

  7. Beta-2-Glycoprotein I Antibody (IgM)

    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

  8. 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

  9. 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

  10. 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
