What is the diagnostic accuracy of the currently available rapid antigen tests relative to viral genetic PCR test as a reference test for the diagnosis of COVID-19/SARS-CoV-2 in adults (18+)?
All races, ages over 18, and geographic locations will be included. Pregnant women when they cannot be separated from the general study population will be excluded.
Index Test: The tests that will be assessed are any SARS-CoV-2 antigen test that can be done within 1 hour of sample collection. Tests can use the following bodily fluids including blood, saliva, mucus, urine, and feces.
Reference Test: The reference test will be commercially distributed PCR based tests that detect the RNA genome of the SARS-CoV-2 and have been validated by an independent third party.
The diagnoses of interest are COVID19 disease and SARS-CoV-2 infection. Diagnosis of influenza will be excluded.
