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 U.S. Food and Drug Administration. This assay has been validated pursuant to CLIA regulations and is used for clinical purposes.
Setup Schedule
Set up: Daily; Report available: 1 day
Reference Range
| EBV DNA, QN PCR | Not Detected (copies/mL) |
| EBV DNA, QN PCR | Not Detected (Log copies/mL) |
Clinical Significance
Monitoring EBV DNA levels by quantitative PCR in patients at risk of EBV-associated lymphoproliferative disorders may allow timely recognition of virus reactivation and permit installment of antiviral treatment. Reportable Range is 200-2,000,000 copies/mL (2.30-6.30 Log Copies/mL).
