Dr. Kirsten Schaffer:

I agree that there is an indication for antigen testing as well but we must be aware of the limitations of our tests. These rapid antigen tests are very good at detecting cases when there is a very high viral load. The antigen test is quite sensitive in detecting such cases. However, they are not as good at detecting cases in individuals who might have a low viral load. We must know when we would want to use the antigen test. There are scenarios in which we could use the antigen test as a screening test to determine if somebody is infected and has a high viral load. It is definitely something that we could consider incorporating into our testing strategy.
