Clinical Evaluation of the Panbio™ COVID-19/Flu A&B Rapid Panel Professional Use Product Using Mid-Turbinate Nasal Swabs

This study is designed as an international, prospective, multicentric, clinical study to investigate the performance of the Panbio™ COVID-19/Flu A\&B Rapid Panel for the qualitative detection of COVID-19 antigen, Influenza A antigen, and Influenza B antigen in human mid-turbinate nasal swabs collected by a trained health worker. This study is part of the performance evaluation to support the CE conformity assessment procedures.

A minimum of 1531 male and female subjects will be prospectively enrolled at multiple clinical sites to assess the performance of the Panbio™ Rapid Panel in detecting predominant Covid-19 and Flu variants currently in global circulation. A minimum of 120 Flu A reference positive subjects, a minimum of 120 Flu B reference positive subjects and a minimum of 300 SARS-CoV-2 reference positive subjects will be enrolled. In addition, a minimum of 991 reference negative subjects will be enrolled.

After informed consent has been obtained, operators will collect one mid-turbinate nasal swab sample from both nostrils from each subject. The nasal collection procedure will be a mid-turbinate nasal swab (deep nasal swab), by turning the swab five times in each nostril. Mid-turbinate nasal samples must be collected prior to the NP sampling. The collected mid-turbinate nasal swab will be tested with the Panbio™ Rapid Panel by an operator at the study site in a Near Patient Testing setting (e.g. GP centre or hospital clinic).

After the mid-turbinate nasal sampling, the operators will collect one NP swab sample from one nostril of each subject. NP sampling should be performed by trained healthcare professionals who routinely conduct NP sampling as part of their other standard of care and clinical duties. The collected NP swab will be eluted in UTM, provided by Abbott/the Core Laboratory, labelled and stored, according to the laboratory manual. UTM samples will be shipped to the Core Laboratory for testing with RT-PCR protocols for Flu A, Flu B and SARS-CoV-2, as per the laboratory manual. The RT-PCR methods used by the Core Laboratory will be CE marked and FDA cleared, with COVID-19 and Flu assay clearance for NP specimens. Leftover UTM from running RT-PCR should be labelled with subject ID and frozen at -80oC.Discordant results will be investigated as outlined in the laboratory manual.

All other aspects of the subject's care will remain the same with no deviation from prescribed practice. If additional Nasal/NP sampling is required, this must be done after the study procedures outlined in this clinical protocol.

Each operator who performs a Panbio™ COVID-19/Flu A\&B Rapid Panel test will fill out a user evaluation questionnaire once, to assess the usability of the device.

Each subject's demographic information, symptomology data, and professionally performed test result and questionnaire will be recorded on source documentation and transferred to an Electronic Data Capture system.
