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
BK Virus DNA,QN RT PCRNot Detected (copies/mL)
BK Virus DNA,QN RT PCRNot Detected (Log copies/mL)


Clinical Significance
This test is used to determine the presence of BK Virus DNA in patient's specimens. Detection of the virus in these specimens may be indicative of an active infection, as PCR detects the presence of the virus, and not the host's reaction to the virus. Polyomavirus BK DNA detection in urine or plasma is associated with an increased risk of graft rejection in renal recipients. Quantitative testing may indicate change in risk over time. This is a quantitative molecular test, with a linear range of 500-500,000,000 copies/mL.
