Remove a polyester swab provided in the rapid antigen kit and flocked swab from the purple ESwab kit. Using both swabs, simultaneously swab the posterior pharynx, tonsils and inflamed areas.
Avoid touching the tongue, cheeks, teeth and any areas that are bleeding with the swab.
Place the polyester swab back in the wrapper for rapid antigen testing. Place the flocked swab into the ESwab tube and break off the shaft at the red score point. If the RAPST is negative, refer the ESwab for confirmatory testing by PCR to the nearest performing site.
See ESwab collection video for more informationFor more information on Specimen Collection Media/Swab, see Specimen Transport Pictorial.
Negative Antigen tests will be confirmed with a follow up by PCR.
