How effective would it be to implement antigen-based COVID-19 point-of-care testing for airport arrivals? Although antigen tests are very specific for the virus, one respondent points out that they are not as sensitive as molecular PCR tests. This means that there is a higher chance of false negatives with antigen testing and negative results may need to be confirmed with a PCR test. Therefore, pooled PCR testing might be a better option for airport screening.
