Varicella Zoster Virus (VZV) assay kits are intended for the diagnosis of diseases induced or associated with VZV infection, such as varicella (chickenpox), herpes zoster (shingles) and the disease complications (pareses, neuropathies, encephalitis, myelitis, cerebellitis, pneumoniae, uveitis) and generalized infections in immune-compromised patients. The kits can also be used for differential diagnosis of neuroinfections, infections of eye and skin and exanthematous diseases.
