Clinical significance:
Varicella-Zoster Virus DNA, Quantitative Real-Time PCR [19493X] - Varicella-Zoster virus (VZV) is a member of the Herpesviridae family that causes chickenpox as a primary infection and can reactivate later in life as herpes zoster or shingles. VZV infection in immunocompromised individuals often leads to a progressive disease state involving multiple organs. The detection of Varicella-Zoster Virus (VZV) DNA is based upon the real-time amplification and detection of specific VZV genomic DNA sequences by PCR from total DNA extracted from the specimen. The quantitative range of this assay is 500-2,000,000 copies/mL.
