Evaluation of the INDICAID™ COVID-19 Rapid Antigen Test

Completed

Conditions: Covid19

Interventions: Diagnostic Test: INDICAID™ COVID-19 Rapid Antigen Test

Registration Number: NCT04904510

Lead Sponsor: University of California, Los Angeles

Brief Summary: The INDICAID™ Rapid Antigen Test was used in real-world outbreak testing. The antigen test was used together with PCR testing. This study was designed to evaluate whether the addition of a rapid antigen test decreased time to results in a real-world setting.

Detailed Description: Description of the INDICAID™ COVID-19 Rapid Antigen Test The INDICAID™ Rapid Test by PHASE Scientific is a LFA designed for the qualitative detection of SARS-CoV-2 nucleocapsid protein in nasal swab samples.

Sample collection and procedure To collect a sample, a nasal swab sample is collected by inserting the provided swab 1 inch into the nasal cavity. The swab is rubbed against the inside walls of both nostrils 5 times in a large circular path. The swab is then dipped into a buffer solution to elute the sample. Finally, three drops of the buffer solution-specimen mix are applied to the LFA test device. After 20 minutes, the user observes the test device for the presence or absence of a test line that indicates detection of the SARS-CoV-2 antigen. An Internal Quality Control line is included to indicate whether the test has been performed correctly.

COVID-19 outbreak screening with the LFA In this Dual-Track testing approach, the LFA is used to identify preliminary positives to trigger prioritization of sample processing for subsequent RT-PCR confirmatory testing.

In Approach A, a preliminary positive result from the LFA would expedite the corresponding patient VTM sample for laboratory-based RT-PCR. Expedited testing would obtain results. In Approach B, a preliminary positive result from the LFA result would trigger the testing of the corresponding patient VTM sample with an onsite rapid nucleic acid amplification test (cobas® SARS-CoV-2 \& Influenza A/B Nucleic acid test on the cobas® Liat system, Roche Molecular Diagnostics). In addition to the onsite rapid RT-PCR test, the corresponding patient VTM sample was also sent for expedited laboratory-based RT-PCR testing. All samples testing negative with the LFA were sent for RT-PCR testing.
