PCR tests for Covid-19 are pretty accurate, but supplies can be scarce and results sometimes aren’t available in time to be useful. Faster tests are available, but are less accurate, so some have argued against their use. We disagree because, in a pandemic, frequency and speed of testing matter more than pinpoint accuracy. As we try to reopen schools and businesses we need to take a hard look at how we’re conducting testing.
