Inclusion Criteria:

• 18 years of age or older
• Male or Female
• Willing and able to provide informed consent
• Symptomatic or asymptomatic
• The EUA RT-PCR sample must be collected within one (1) day of the sample collected for testing by the Nanomix eLab® COVID-19 Rapid Antigen Panel.

Exclusion Criteria:

• Subjects without both a valid EUA RT-PCR test result and a valid Nanomix eLab® COVID-19 Rapid Antigen results will be excluded

The study population will include both symptomatic and asymptomatic subjects. Although to enrich for COVID-19 positive subjects, the study will preferentially identify and enrolled subjects who have been or will be tested by EUA RT-PCR including those who are symptomatic or hospitalized with symptoms, specifically those within 7-days of symptom onset that meet the study enrollment inclusion and exclusion criteria.
