Method: Real-Time Polymerase Chain Reaction (PCR)
Limit of Detection: 2.8 log copies/mL (576 copies/mL)
Quantitative Range: 3.0 – 7.8 log copies/mL (1,000 - 62,800,000 copies/mL)
Plasma – 85.9%/100% (n=15)
Urine – 95.7%/100% (n = 23)
A negative result (virus not detected) does not rule out the presence of BK Virus concentrations below the level of detection by the assay or the presence of inhibitory substances. Inhibition may also lead to underestimation of viral quantitation. Viruses detected at levels below 1,000 copies/mL are not quantitated.
Caution should be taken when interpreting results generated by different assay methodologies.
Assay methodology is polymerase chain reaction (PCR) performed pursuant to a license agreement with Roche Molecular Systems, Inc. This test, which uses Analyte Specific Reagents, was developed and its performance characteristics determined by Legacy Laboratory Services.
