Specimen Collection, Storage, & Shipment
Because specimen submission requirements for CLIA diagnostic testing are currently being updated, ALL submissions to CDC for diagnostic testing require pre-approval at this time. Please contact PicornaLab@cdc.gov before submitting AFM specimens to CDC.
Refer to this table when you collect, store, and ship specimens. Please check back periodically for updates to acceptable specimen types. Before sending specimens to CDC, please contact PicornaLab@cdc.gov.
Note that CDC will use real-time PCR for generic testing and nested PCR for typing.
