- Flu A/B
Confirm presence of influenza A or influenza B
Real-time reverse-transcriptase polymerase chain reaction (RT-PCR)
Nasopharyngeal swab, nasal swab, throat swab, or combined throat/nasopharyngeal swab
Specimen should be collected during acute phase of the disease, ideally within 24 hours of onset of symptoms. Guide the flexible (ideally a flocked rather than wound) swab into the contour of the nares and into the nasopharynx. Leave in place 15 to 30 seconds, rotate and remove. Place swab in viral transport.
Throat swab: Carefully rub the posterior nasopharynx with a dry sterile swab (preferably the "flocked swab"). Avoid touching the tongue or buccal mucosa. Place swab in viral transport.
Causes for Rejection
Bacterial swab transport; source other than those listed above; grossly leaking transport container; dry specimen; specimen submitted in fixatives; specimen in other than a suitable viral transport device; specimen received after a prolonged delay; unlabeled specimen
