Varicella-Zoster Virus by PCR : 0060042

Mnemonic: VZVPCR

Methodology: Polymerase Chain Reaction
Performed: Mon, Wed, Fri
Reported: 1-4 days
Specimen Required: Collect:  CSF, ocular specimen, vesicle fluid, or tissue biopsy.  Freeze tissue immediately.  Specimen source is required.

Transport:  1 mL CSF or ocular specimen in sterile container, frozen. Vesicle fluid, or tissue biopsy in viral transport media (Microtest M4 or UTM) (ARUP supply #12884), frozen. Transport fresh, snap frozen tissue on dry ice.

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Pediatric Collection/Transport:  0.25 mL CSF, ocular specimen in sterile container, frozen.  (Less volume may decrease sensitivity of assay.)

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Unacceptable Conditions:  Nonsterile or leaking containers. Heparinized or hemolyzed specimens. Tissue in formalin or other preservatives.

Stability:  Ambient: 8 hours (excludes tissues); Refrigerated: 3 days (excludes tissues); Frozen: 3 months
Reference Interval:
Negative - Varicella-zoster virus DNA not detected by PCR.
Positive - Varicella-zoster virus DNA detected by PCR.
Interpretive Data: A negative result does not rule out the presence of PCR inhibitors in the patient specimen or varicella-zoster virus DNA concentrations below the level of detection of the assay.

This test is performed pursuant to an agreement with Roche Molecular Systems, Inc.

Please refer to Statement B in the Compliance Statements section in the front of the Laboratory Test Directory.
