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. Polyomavirus BK DNA detection in plasma, serum and whole blood is associated with an increased risk of graft rejection in renal transplant recipients.
