We have been trying to get a postal test after DC picked up a cough from school. We can't send them back until we get the all-clear (which I understand). I've been trying to get a test for two days, but every time I log on, there are no postal tests and it says all our local testing centres are full. It isn't even giving me an option to travel to a further one, just to come back and re-check later.
This worries me on a wider issue. How are we supposed to know how many people have covid if (I presume) lots of people like us are unable to get tests? How can we trust the figures of new cases if tests are no longer widely available?
