Test Information
​ For rapid detection of renal disease due to BK Virus. This test is not to be used as a diagnostic tool for Creutzfeldt - Jakob disease (CJD). The assay detects > 10 genomic equivalents of the virus. Urine specimens may have very high copy levels of BKV DNA (10[6]-10[8] copies/mL). Because viral load levels may overlap in symptomatic versus asymptomatic patients (poor specificity) BKV DNA in urine may not be clinically helpful as an indicator of PVAN. However, detection of BKV DNA in urine may provide early evidence of infection with this virus. Unlike urine, the presence of BKV DNA in plasma at levels > or =16,000 copies BKV DNA/mL is very specific for PVAN.
Reference Range Information
Performing Location Reference Range
​Mayo Medical Laboratories ​Negative
Interpretation
Results of urine tests are reported in terms of the presence or absence of BK virus (BKV).
 
Detection of BKV DNA in clinical specimens may support the clinical diagnosis of renal or urologic disease due to BKV. Correlation of qualitative results with clinical presentation and BK viral load in urine and/or plasma is recommended.
