Yes; the lateral flow tests that are being used in Liverpool are accurate. They measure whether somebody is infectious and have a very high specificity. We publish all these statistics, having had them assessed at Porton Down in one of the best medical science units across the whole world, so I assure the hon. Gentleman—and, through him, his constituents —that the lateral flow tests have a quick turnaround and a high degree of accuracy regarding whether someone is infectious. I have not seen the reports to which he refers, but I assure him that the best thing that people can do if they are offered a test is to get one.
