Really appreciate you digging into this. We aren’t planning to run the test, just trying to evaluate the options available. We are a research lab, not a diagnostic lab.I spend a couple of hours last night. I share your concerns. I posted one article that illustrates the concern. Antigen tests are widely variable. What test equipment and test are you looking to purchase or do you own?
I will ask my SMEs today so see if there is an answer. The incubation period is 4-7 days so that is when people should get symptomatic. What you are asking for is a rule-out test and I am not aware of a good one. I would insist on a PCR. You want specificity to confirm infections. The bottom line is that the best rule out infection is 14 days of quarantine. Even that misses the asymptomatic.
If you are looking for an option, there is one antigen test that may soon be readily available that gets to 80% sensitivity: Sofia 2 SARS Antigen FIA. It was announced in May. I am not sure on availability.
