I have a young adult child in a rehabilitation unit following a serious injury a year ago. They will not allow me to visit even tho my child contracted COVID whilst in hospital and is now negative.l. Nor will they allow me in with a negative test of my own. My question is this. I want to be able to 'unwrap' a test in front of the staff and do the test 'there and then' that shows I am negative. I was wondering if these new 'lateral flow' tests coming in will allow me to do this? I live in an area where these are being rolled out. Can anyone help? Does anyone know how these tests work?
