Limitations
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

Reference Range
Not Detected


Clinical Significance
This test is used to determine the presence of BK Virus DNA in patients' 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.  
  
This is a quantitative molecular test, with a linear range of 500-500,000,000 copies/mL (2.70-8.70 Log copies/mL)
