Clinical Feasibility of the BinaxNOW™ COVID-19/Flu A&B Combo in the Southern Hemisphere

Approximately 700 symptomatic participants will be enrolled to achieve at least 61 COVID PCR positive, 45 Flu A PCR positives, 30 Flu B PCR positives and 301 COVID and Influenza PCR negatives.

The total number of research-related anterior nasal swabs collected from each consented Participant is two (2). Participants ages two (2) years and older meeting eligibility criteria will be enrolled.

The order of nasal swab collection will be randomized according to the Participant ID as to which swab is used for BinaxNOW™ COVID-19/Flu A&B Combo and which is to be eluted into VTM/UTM and will have the swab head left in the media (snap off or clip shaft) for comparator testing.

For Participants with an odd numbered Participant ID, the first swab will be self-collected and used for the BinaxNOW™ COVID-19/Flu A&B Combo. The second swab will be collected by a healthcare professional and eluted into VTM/UTM and will have the swab head left in the media (snap off or clip shaft) for comparator testing. The Participant will review the Instructions for Use, collect the nasal swab, and perform the BinaxNOW™ COVID-19/Flu A&B Combo, then interpret and record the result at the time specified in the product instructions.

For Participants with an even numbered Participant ID, the first swab will be collected by a healthcare professional and eluted into VTM/UTM and will have the swab head left in the media (snap off or clip shaft) for comparator testing. The second swab will be self-collected and used for the BinaxNOW™ COVID-19/Flu A&B Combo. Once the healthcare provider collected the swab for the comparator test the Participant will review the Instructions for Use.

The VTM/UTM samples will be stored, handled, and tested with comparator assays according to the manufacturers' product instructions. VTM/UTM specimens can be stored for up to 48 hours at 2-8°C. If delivery and processing of samples exceeds specified time periods, specimens should be transported in dry ice and once in laboratory frozen at -70°C or colder.

Each Participant's demographic data, inclusion/exclusion data, days of symptom onset, comparator results, Education level, occupation, and socioeconomic status and other data points will be documented on the data collection worksheets and EDC.
