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 FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
Mon-Sat
Report Available
2-3 days
Reference Range
| Herpesvirus 6 DNA, QN RT PCR | Not Detected (copies/mL) |
| Herpesvirus 6 DNA, QN RT PCR | Not Detected (Log copies/mL) |
Clinical Significance
This test is used to determine the presence of HHV-6 DNA in patients' specimens. Organisms may be detected by PCR prior to detection by immunological methods. PCR provides more rapid results than other methods, including culture.
