The quantitative range of this assay is 2.6-8.6 log copies/mL (390-390,000,000 copies/mL). A negative result (less than 2.6 log copies/mL or less than 390 copies/mL) does not rule out the presence of PCR inhibitors in the patient specimen or BK virus DNA concentrations below the level of detection of the assay. Inhibition may also lead to underestimation of viral quantitation. No international standard is currently available for calibration of this assay. Caution should be taken when interpreting results generated by different assay methodologies. This test is performed pursuant to an agreement with Roche Molecular Systems, Inc. Please refer to Statement A in the Compliance Statements section in the front of the Laboratory Test Directory. |
