87798 (qualitative BK virus PCR); 87799 (quantitative BK virus PCR)
Amplification and detection of BK virus DNA using real-time TaqMan PCR and nucleic acid primer/probe pairs specific for conserved regions of the BK virus genome. This test is performed pursuant to an agreement with Roche Molecular Systems, Inc.
If positive, results are reported as BK virus DNA detected.
Negative or no BK virus DNA detected
Clinical Utility: BK virus can cause ureteral ulcerations, stenosis, and hemorrhagic cystitis in renal transplant recipients. Persistent active replication of BKV in renal transplant recipients also has been associated with progressive loss of the graft due to BKV-associated nephropathy. BKV-associated hemorrhagic cystitis is a major complication of bone marrow transplants. Continuous monitoring of urine and plasma by real-time PCR is desirable to predict disease and follow recovery over time. Kidney tissue can also be tested.
