Butterfly - Clinical Performance Study

The Applied Biosystems™ TaqPath™ COVID-19 Diagnostic PCR Kit (referred to as "COVID-19 test") aims to develop a reverse transcription, real-time polymerase chain reaction (RT-qPCR) test for the qualitative detection of SARS-CoV-2.

The purpose of this study is to evaluate the clinical performance of the TaqPath™ COVID-19 Diagnostic PCR Kit (COVID-19 test) in nasopharyngeal swabs and anterior nasal swabs from symptomatic individuals suspected of COVID-19 by their health care provider.

A composite comparator approach will be used to evaluate the performance of the COVID-19 test which includes the use of three highly sensitive SARS-CoV-2 molecular assays as comparators. Clinical calls will be compared between COVID-19 test and the three composite comparators. The third comparator assay will only be used to test samples that show discrepant clinical calls between the first two comparator methods, for a two-out-of-three result interpretation. The Clinical Performance Study Protocol (CPS Protocol) outlines the clinical sample collection and testing protocols which will be used to satisfy the FDA 510(k) study requirements in the US.
