I'm really concerned that these innacurrate tests will override the need to self isolate. I have to tick a box to confirm that if a close contact to me tests positive I will continue to go into work and have a test every day for 10 days. Previously we were told the chances of catching it from someone you live with if they are positive are almost 100%. Now I'm being told that even if husband was positive I should attend work until I also test positive? Surely this will just make the whole situation worse?
