Are these PCR based tests? What is the accuracy rate? I was told it is far from 100%.
So is it possible that someone might test negative but then is actually asymptomatic?
This is exactly what happened last year in South Korea. People were tested many times and they were negative but turned out they were asymptomatic that the test kit failed to pick up.
