Rapid Covid tests miss 90% of asymptomatic cases
What I think really matters for most people is not to find out whether they have covid or not, but whether they are infectious or not. I&#x27;d really like to see research (any at all!) into how effective different test methods are at predicting infectiousness and am disappointed that this never seems to get addressed.<p>Because who cares if you&#x27;re asymptomatic but your viral load is low and you&#x27;re unlikely to infect others? If lack of viral load is the reason that the test is a false negative but that&#x27;s also correlated with low likelihood that you can infect others, then this understanding is not useful. The test still did it&#x27;s job for what people needed it for.<p>The full article does not seem to be publicly accessible, so I&#x27;m not sure if my comment is already covered.
