Laboratory Testing

Infection with non-polio enteroviruses can be confirmed by:

  • isolating or identifying the virus in cell culture, or
  • polymerase chain reaction (PCR) assay.

Specimen Collection

Non-polio enteroviruses can be detected in stool or rectal swabs and respiratory specimens (including from the throat). Depending on the symptoms, other specimen types, such as cerebrospinal fluid, blister fluid, and blood, can be collected for testing. For more information, see Specimen Collection, Storage, & Shipment.

A positive laboratory test for non-polio enteroviruses from certain specimens, such as rectal or respiratory swab, does not necessarily mean the virus is the cause of infection. Non-polio enteroviruses can be shed for an extended period of time after the symptoms have resolved.
