Test ID: FVZD
Varicella Zoster Antigen, DFA
Specimen Type 
Describes the specimen type needed for testing
Varies
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Submit only 1 of the following:
Swab or specimen in suitable viral transport media (VTM), VCM transport
medium or equivalent. Vesicular lesion, fluid of lesion, swab of lesion,
swab of fluid
Acceptable: Air dried smear, eye swab
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
3 mL VTM, 1 swab in VTM or 1 slide
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis | NA |
| Thawing | NA |
| Lipemia | NA |
| Icterus | NA |
| Other | Frozen or broken slides; dried swabs; specimens received past stability or at unacceptable temperature conditions; nucleic acid transport; gel swabs. |
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
| Specimen Type | Temperature | Time |
|---|---|---|
| Varies | Refrigerated | 72 hours |
