## Indications for use
The DiaSorin LIAISON® VZV IgG uses chemiluminescence immunoassay (CLIA) technology on the LIAISON® Analyzer family for the qualitative detection of specific IgG antibodies to varicella-zoster virus (VZV) in human serum. This assay can be used as an aid in the determination of previous infection of varicella-zoster virus. 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 DiaSorin LIAISON® Control VZV IgG (negative and positive) is intended for use as assayed quality control samples to monitor the performance of the DiaSorin LIAISON® VZV IgG assay on the LIAISON® Analyzer family. The performance characteristics of the LIAISON® Control VZV IgG have not been established for any other assays or instrument platforms different from LIAISON® and LIAISON® XL.
