FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
Set up: Daily; Report available: 1 day
Reference Range
| HSV 1 DNA, QN PCR, CSF | Not detected |
| HSV 2 DNA, QN PCR, CSF | Not detected |
Clinical Significance
The detection of HSV-1 and HSV-2 DNA is based upon the real-time amplification, detection, and differentiation of specific HSV-1 and HSV-2 genomic DNA sequences by PCR from total DNA extracted from the specimen. The quantitative range of this assay is 100 - 2,000,000 copies/mL.
