Are you testing for very mild cold symptoms, for example, even if multiple LFTs are negative? Or do you stick to the three 'official' symptoms listed?
I have ridiculous sinuses and if I PCR'd every time I had a bunged up/slightly runny nose I'd be forever isolating. I do LFTs two or three times a week (daily if I'm having a sinus flare) though.
DD had a very, very mild cold last week (slight runny nose/a bit stuffy first thing, no illness as such) and did daily LFTs (all negative).
How do you decide when to PCR?
