I’ll say it again:
Rapid tests have the same accuracy in asymptomatics as symptomatics
If someone says they are less sensitive to detect infectious people who are asymptomatic, they are wrong
The test does not care about your symptoms, it cares about how much virus you have

The above comment is referring to “same accuracy to identify infectious individuals”.
The reason numerous papers say they are less accurate in asymptomatics is because of sampling bias. Asymptomatics are much more frequently tested *AFTER* they are no longer infectious.

s PCR remains positive for weeks, meanwhile infectiousness lasts only 3-7 days - and thus rapid tests are only positive for 3-7 days or About 30% of the time that ppl are PCR positive.

W/out symptoms, it’s a random sample along the PCR positive timeline and thus looks like rapid tests miss 70%. Even if they were to detect 100% of contagious ppl.
