Enteroviruses are detected by reverse-transcriptase real-time polymerase chain reaction (PCR) amplification of a 94-base portion of the 5' untranslated region of the enteroviral genome. There are more than 60 human enteroviruses. This procedure cannot differentiate individual enterovirus types. The analytical sensitivity of this assay is 150 copies/mL.
