CDC Laboratory Testing & Procedures

Laboratory Testing

CDC laboratories routinely conduct testing for non-polio enteroviruses and parechoviruses, including

  • qualitative molecular testing; pan-enterovirus and pan-parechovirus
  • molecular testing, followed by sequencing to identify enterovirus and parechovirus types (formerly serotypes)
  • testing for less common picornaviruses (excluding Hepatitis A)

CDC also helps state laboratories by

  • transferring new diagnostic technologies and providing training on how to perform these techniques,
  • helping them identify enteroviruses and parechoviruses they have not been able to type, and
  • providing guidance on how to properly collect and ship clinical specimens to CDC for confirming and typing picornaviruses.
