Not detected

The Xpert EV Assay is designed to detect enterovirus (EV) RNA (enterovirus genome 5' untranslated region between nucleotide 452 and 596) in CSF samples. The assay detects most enteroviruses, including echoviruses, coxsackie A viruses, and coxsackie B viruses. The assay does not distinguish between serotypes.

Results from the Xpert EV assay should be interpreted in conjunction with other laboratory and clinical data. Positive enterovirus PCR results do not rule out other causes of meningitis, including bacteria, mycobacteria, other viruses (herpes family viruses, arboviruses, mumps virus, etc) and fungi. Rare occurrences of simultaneous mixed bacterial- viral meningitis have been reported in the literature.

This test is only performed on CSF. For detection of enteroviruses in blood, order Enterovirus Detection by RTPCR.
