Useful for:

This assay is used for the detection of Varicella zoster virus (VZV) DNA in cerebrospinal fluid.

Limitations:

Results from this test must be considered in conjunction with the clinical history, epidemiological data and other laboratory information available to the clinician evaluating the patient.

Negative results do not rule out VZV infections of the CNS and should not be used as the sole basis for treatment or other patient management decisions.

False-negative results may occur if the viruses are present at a level that is below the analytical sensitivity of the assay or if the virus has genomic mutations, insertions, deletions, or rearrangements or if performed very early in the course of illness.
