Why don't we have cheap/free, widespread, rapid home testing yet? We've known about Covid-19 for almost a year!
Then people could just test themselves before traveling or going to indoor gatherings. They could also be used at airports, etc.
- bsder 6y agoEven if you do, the tests aren't biased that way. If the tests give you a positive result, you almost certainly have Covid. However, a negative result doesn't imply lack of Covid with the same accuracy.
- stronglikedan 6y agoI've read that the rapid (antigen) testing is not as accurate as the tests that are processed in a lab. I've seen figures of up to 37% false negatives. I would have looked into it more, but I've decided that I would personally not trust a rapid test if a lab test was available, except in the most urgent of scenarios.
