Brief summary
The purpose of this study is to evaluate the usability of the MGC Health COVID-19 & Flu A+B Home Multi Test in home use.
Detailed description
The MGC Health COVID-19 & Flu A+B Home Multi Test is a lateral flow immunochromatographic antibody assay intended for the simultaneous qualitative detection and differentiation of the nucleocapsid antigen from SARS-CoV-2, influenza A and/or influenza B directly from anterior nasal swab specimens obtained from individuals, who are suspected of respiratory viral infection within five (5) days of symptom onset. This test is intended for non-prescription home use with self-collected direct anterior nares swab samples from individuals ages 14 years and older or adult lay user collected anterior nares swab samples from individuals aged 2 to 13 years. The objective of the study is to determine the usability of the MGC Health COVID-19 & Flu A+B Home Multi Test in a simulated home use environment. This is an open label study to evaluate the usability of the MGC Health COVID-19 & Flu A+B Home Multi Test using information from the Quick Reference Instructions (QRI).

| Usability of Quick Reference Instructions (QRI) - Subject Test Result and Observer Confirmation | 1 hour | Assess the usability of the QRI based upon observer evaluation. |
| Usability of Quick Reference Instructions (QRI) - Critical Steps | 1 hour | Assess the usability of the Quick Reference Instructions (QRI) based upon observer evaluation. The observer completed an observation form for each subject assessing whether the subject or adult lay user completed each critical task, and whether the task was performed correctly. |
| Usability of Test Kit | one hour | Assess the usability of the kit for home use based upon subject evaluation. adult lay users filled out a questionnaire regarding the ease of understanding the instructions provided by the QRI for obtaining the sample, performing the test, and reading and interpreting the results, and the ease of completing each task. The subject or adult lay user used the following 5-digit score to answer the questions: 1. Very easy to understand 2. Fairly easy to understand 3. Easy 4. Fairly difficult to understand 5. Very Difficult |
| Usability of Quick Reference Instructions (QRI) - Interpretation of Example Test Results | 1 hour | Assess the usability of the QRI. Subjects or adult lay users were presented with 10 sample images of test results: 1 negative test, 7 positive tests, and 2 invalid tests. |
