Deck the Swabs!

There is a somewhat disturbing tale from the UK's Milton Keynes Covid-19 testing centre that appears to have lots of capacity waiting expectantly but only a relatively few swabs to test each day (https://www.theguardian.com/commentisfree/2020/apr/16/swab-tester-uk-germany-south-korea). Testing and tracking are advocated as effective ways of helping to deal with the pandemic (as revealed in the recent experiences of Germany and South Korea) but the UK's problem seems to be rooted in the collection of samples in sufficient numbers and transporting them safely to the centres. The results  also need to be gathered, returned swiftly and acted upon if there is to be any point to the process.
