I’ve had a letter asking if I will take part in a study by Imperial College London comparing two home tests swab of nose & throat vs saliva. It says the swab ‘May cause some mild short lived discomfort’. I’ve heard that it’s quite unpleasant. i feel like I should do it as I’ve been asked but considering sore throat is one of my symptoms slightly concerned I might struggle with the swab. it’s the test to see if you currently have CV but doesn’t register if you’ve previously had it. I don’t think I’ve got it or have had it I’ve had little contact with people since lockdown and not been inside any buildings other than home.
