The LIAISON® VZV IgG HT assay uses chemiluminescent immunoassay (CLIA) technology for the in vitro qualitative detection of specific IgG antibodies to varicella-zoster virus (VZV) in human serum (with gel and without gel-SST), dipotassium EDTA (K2- EDTA), lithium heparin and sodium heparin plasma samples. This assay is intended as an aid in the determination of previous infection of varicella- zoster virus. The test must be performed on the LIAISON® XL Analyzer. The assay performance in detecting antibodies to VZV in individuals vaccinated with the FDA-licensed VZV vaccine is unknown. The user of this assay is responsible for establishing the performance characteristics with VZV vaccinated individuals.

The Diagnostic Hybrids, Inc D3 DFA Varicella-zoster Virus Identification Kit is intended for use in the qualitative detection of varicella-zoster virus (VZV) in cell cultures by immunofluorescence using fluoresceinated monoclonal antibodies (MAbs). Negative results do not preclude an infection and should not be used as the sole basis for diagnosis, treatment or other management decision. Performance testing has not been done on direct patient specimen testing.

The Diagnostic Hybrids, Inc. D3 DFA VARICELLA-ZOSTER IDENTIFICATION KIT includes a DFA Reagent that contains a blend of two fluorescein-labeled murine monoclonal antibodies directed against VZV antigens. The kit includes the following components: VZV DFA Reagent, Mounting Fluid, VZV Antigen Control Slides, PBS Concentrate.

The Zeus Scientific Varicella Zoster Virus (VZV) IgM ELISA Test System is intended for the qualitative detection of IgM class antibodies to Varicella Zoster Virus in human serum as an aid in the diagnosis of primary infection or reactivation. The assay performance in detecting antibodies to VZV in individuals vaccinated with the FDA licensed VZV vaccine is unknown. The user of this assay is responsible for establishing the performance characteristics with VZV vaccinated individuals. The assay performance in detecting antibodies to VZV in cord blood and neonates has not been established.

The Zeus Scientific VZV IgM ELISA Test System is an enzyme linked immunosorbent assay intended for the qualitative detection of distict IgM antibody to the Varicella-zoster virus. The test is designed to detect IgM antibody using inactivated VZV antigen: strain, Ellen.

The LIAISON® VZV IgG Assay uses chemiluminescence immunoassay (CLIA) technology on the LIAISON® Analyzer for the qualitative detection of specific IgG antibodies to varicella-zoster virus in human serum. This assay can be used as an aid in the determination of previous infection of varicella-zoster virus.

The method for the qualitative determination of specific IgG to varicella- zoster virus is an indirect chemiluminescence immunoassay (CLIA). All assay steps and incubations are performed by the LIAISON® Analyzer. Varicella-zoster virus antigen is used for coating magnetic particles (solid phase) and a mouse monoclonal antibody to human IgG is linked to an isoluminol derivative (isoluminol-antibody conjugate). During the first incubation, anti-VZV IgG antibodies, present in calibrators, samples or controls, bind to the solid phase. After each incubation, the unbound material is removed with a wash cycle. During the second incubation, the antibody conjugate reacts with anti-VZV IgG already bound to the solid phase. Subsequently, the starter reagents are added and a flash chemiluminescence reaction is induced. The light signal, directly related to the amount of isoluminol-antibody conjugate, is measured by a photomultiplier as relative light units (RLU) and is indicative of the presence of anti-VZV IgG in calibrators, samples or controls.

Light Diagnostics SimulFluor™ HSV/VZV Immunofluorescence Assay is a direct immunofluorescence test intended for the simultaneous detection and identification of HSV 1 and 2 and varicella-zoster virus (VZV) from patients with vesicular, oral, genital, or skin lesions, and following amplification of virus in culture. Specimens found to be negative on direct specimen examination should be tested by cell culture.

Light Diagnostics SimulFluor™ HSV/VZV Immunofluorescence Assay utilizes a single reagent for the simultaneous detection and identification of HSV and VZV. The primary component, specific for both HSV 1 and 2 will bind to 155kD major capsid protein in HSV-infected cells. The secondary component, specific for VZV, will bind to glycoprotein gp I and the immediate early antigen in VZV-infected cells. Unbound reagent is removed by rinsing with phosphate-buffered saline (PBS). Illumination with ultraviolet light allows visualization of the antigen-antibody complexes by fluorescence microscopy. When a FITC filter set is used, the HSV antigen-antibody complex will exhibit an apple green fluorescence and the VZV antigen-antibody complex will fluoresce yellow-gold. Uninfected cells stain a dull red due to the presence of Evans blue in the reagent. A blend of monoclonal antibodies directed against HSV and VZV is used in the Light Diagnostics SimulFluor™ HSV/VZV reagent. The use of monoclonal antibodies ensures increased specificity of the reagent and reduces the risk of non-specific background or interference.
