Test Indications:
|
Rapid (qualitative) detection of VZV DNA in clinical specimens.
Varicella Zoster virus (VZV) is a member of the Herpesviridae family that can cause chickenpox as a primary infection and can reactivate later in life as herpes zoster or shingles. VZV infection in immunocompromised individuals. VZV infection in immunocompromised individuals often leads to a progressive disease state involving multiple organs.
