A million coronavirus tests are coming to Britain, but do they work?

I have uncovered another troubling potential roadblock to increasing the volume of tests for Covid-19. It is all quite complicated, so please bear with me. What I have learned is that just under two weeks ago, the Government paid several million pounds to purchase two million ‘rapid lateral flow diagnostic test’ kits from China, with one million coming from a company called Wondfo and one million from AllTest.
