Anyway, you need context.

The 100,000 tests seem to be split.

New LFT Test (claimed to be 99.7% accurate) shows 80% fewer cases than standard PCR test (as used in Sedbergh and rest of UK)

So maybe this will help our decision makers get their act together, although I doubt it. They are too invested in the current track of lockdown until vaccine.
Those who are asymptomatic are having the "lateral flow" test. I have had a look around to try and find its false negative rate, and the commonest figure seemed to be 30%.

There is this, from the BMJ: " A preliminary evaluation from Porton Down and Oxford University9 throws little light on its performance in asymptomatic people or in the field. It suggests the test misses between one in two and one in four cases."
