Clinical Significance
This test detects and quantitates BK Virus DNA in urine specimens of kidney transplant recipients who are at risk of developing BKV-associated nephropathy (BKVAN) and associated hemorrhagic cystitis leading to kidney failure. Prospective viral load monitoring of BKV DNA in urine (and plasma) is useful to exclude a diagnosis of BKVAN and to monitor the course of BKV infection. The assay is calibrated to the First World Health Organization International Standard for BKV DNA with a Reportable Range of 200-100,000,000 IU/mL (2.30-8.00 log IU/mL).
