The LIAISON® Testosterone xt assay's method for quantitative determination of testosterone is a direct, competitive, chemiluminescence immunoassay (CLIA). Specific antibody to testosterone is bound to magnetic particles (solid phase) and testosterone is linked to an isoluminol derivative. During the incubation, testosterone is dissociated from its binding protein and competes with labeled testosterone for binding sites on the antibody. After the incubation, the unbound material is removed with a wash cycle. Subsequently, the starter reagents are added and a flash chemiluminescent reaction is initiated. The light signal is measured by a photomultiplier as relative light units (RLU) and is inversely proportional to the concentration of testosterone present in calibrators, controls, or samples. The LIAISON® Testosterone xt is an in vitro diagnostic device consisting of reagents provided in individual compartments within a plastic container called the Reagent Integral. The components provided in the unitized Reagent Integral include: PMP (paramagnetic particles), conjugate and assay buffer. All reagents in the integral are supplied ready to use. The assay configuration for the LIAISON® Testosterone xt allows for the performance of 100 tests. The two-point calibrators are provided in the same kit box, but separate from the Reagent Integral. The two-point calibrators are supplied ready to use. The LIAISON® Testosterone xt assay is performed on the LIAISON® XL Analyzer (Model 10050; originally FDA cleared under k103529), a fully automated system with continuous loading combining the chemiluminescence technology with magnetic microparticles as the solid phase.

Radioimmunoassay for the quantitative measurement of free testosterone in human serum. This assay is intended for in vitro diagnostic use.

The radioimmunoassay of free testosterone is a competitive assay. The procedure follows the basic principle of radioimmunoassay where there is competition between a radioactive and a non-radioactive antigen for a mixed number of antibody binding sites. The amount of [125]]-labeled testosterone analog bound to the antibody is inversely proportional to the concentration of unlabeled free testosterone present. The separation of the free and bound antigen is achieved by decanting or aspirating the antibody-coated tubes. A standard curve is constructed and unknown free testosterone values are obtained from the curve by interpolation. Kit Content: Free Testosterone Antibody-Coated Tubes: 2 x 50 tubes (ready-to-use) 125|-labeled Testosterone Analog Tracer (YELLOW): one 22 mL vial (ready-to-use) Calibrators: one 1.0 mL vial labeled 0, and seven 0.5 mL vials labeled 1-7 (ready-to-use) Controls: two 0.5 mL vials labeled 1, 2 (ready-to-use)

FastPack® IP SHBG is a chemiluminescent immunoassay intended for the quantitative determination of Sex Hormone Binding Globulin in human serum and plasma on the FastPack® System. The FastPack® IP SHBG assay is intended for use as an aid in the diagnosis of androgen disorders.

The FastPack® IP Sex Hormone Binding Globulin Immunoassay employs a sandwich immunoassay principle. Endogenous SHBG in a patient sample, calibrator, or control is dispensed into a FastPack® reagent pack. In the reagent pack, the sample binds with a monoclonal anti-SHBG antibody covalently linked to alkaline phosphatase (ALP) and a different monoclonal anti-SHBG antibody linked to biotin will bind to streptavidin coated paramagnetic particles (PMP). After incubation, washing steps (using a Tris buffer containing detergents) occur to separate bound from unbound anti-SHBG monoclonal antibody-ALP, a chemiluminogenic substrate mixture is added to the system. This mixture contains indoxyl-3-phosphate, a substrate for ALP, and lucigenin (N,N dimethyl-9,9'-biacridinium dinitrate). ALP dephosphorylates indoxyl-3-phosphate to indol-3-ol, which subsequently undergoes oxidation. As a result, lucigenin is reduced to form a dioxetane structure that is cleaved to yield N-methylacridone. This compound produces a sustained luminescent glow following excitation. The raw relative luminescence units (RLUs) generated are measured by a photomultiplier tube in the FastPack® Analyzer and are directly proportional to the concentration of SHBG in the sample. The entire reaction sequence takes place at 37 ± 0.5 ℃ and is protected from external light.
