Laboratory Diagnosis of Enteroviruses and Parechoviruses Infection
Diagnostic Procedures | Optimal Specimen | Transport Issues and Optimal Transport Time |
---|---|---|
NAAT | CSFa | Sterile tube, RT, <2 h |
Plasmab | EDTA or PPT, ≤2 h | |
Serumb | SST, RT ≤2 h | |
Urine | Sterile container, RT, <2 h | |
Culture | Plasmab | EDTA or PPT, RT, <2 h |
Stool | Sterile container, RT, <2 h | |
Throat swab | Sterile container or viral transport medium, RT, <2 h |
Abbreviations: CSF, cerebrospinal fluid; EDTA, ethylenediaminetetraacetic acid; NAAT, nucleic acid amplification test; PPT, plasma preparation tube; RT, room temperature; SST, serum separator tube.
aA commercial US Food and Drug Administration–cleared product is available for rapid polymerase chain reaction testing for enteroviruses in CSF.
bWhole blood is a less reliable source for detection by culture or NAAT methods.
