Laboratory test results should always be considered in the context of clinical observations. This test was developed, and its performance characteristics determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration (FDA). The FDA has determined that such clearance or approval is not necessary. This test is used for clinical purposes. It should not be regarded as investigational for research. This laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) as qualified to perform high complexity clinical laboratory testing. 

Not Detected.

This test is used in the diagnosis of human herpesvirus 7 infection. HHV-7 is closely related to HHV-6 and CMV and can cause reactivation in transplant patients or other immune-compromised individuals. PCR may detect infection earlier than immunological methods and provides more rapid results than culture but does not provide information on past exposure or immunity. Quantitative measurement may provide information on disease regression. 
Reportable range is 500 to 10,000,000 copies/mL (2.70 to 7.00 Log copies/mL).
