To be fair though, ideally we should be testing random population samples of people who are symptomatic, and some who are suspected to have been exposed but are not symptomatic, to get a better idea of the number of asymptomatic cases. It's vital data. But of course relies on there being a decent availability of tests.

I'm not sure what the point if of testing people with mild symptoms who "just want to know", unless it's because they could be back at work if they know they're covid negative. Knowing doesn't change the treatment pathway at all unless syou end up in hospital - at which point you'd be tested anyway.
