Clinical Significance
Norovirus virus detection was performed by reverse transcriptase polymerase chain reaction (PCR) amplification of a portion of the viral RNA polymerase gene and real-time detection using TaqMan detection probes. This method will detect genogroup 1 and genogroup 2 noroviruses. The analytical sensitivity of this assay is approximately 100 virus copies/assay. Positive results should be correlated with clinical presentation as Noroviruses are excreted in the stool for 2-3 weeks after clinical symptoms resolve. A negative result does not rule out infection.
