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 the CLIA regulations and is used for clinical purposes.
Setup Schedule
Set up: Daily; Report available: 1 day
Reference Range
| CMV DNA, QN PCR | Not Detected | IU/mL |
| CMV DNA, QN PCR | Not Detected | Log IU/mL |
Clinical Significance
In patients who are immunocompromised, CMV may cause disseminated, severe disease. CMV is also the most common cause of congenital viral infection in humans. Quantitative PCR methods may be useful in monitoring CMV replication in immunosuppressed patients or in determining the viral load of CMV in amniotic fluid. This is a quantitative molecular test, with a linear range of 200-2,000,000 IU/mL.
