Met friends at the park yesterday, kids playing together and today one of their kids have a positive LFT. No symptoms. Is it likely we will be close contacts? Should we just book PCRs for tomorrow and get them over with? Or will test and protect (Scotland) contact us if they have a positive PCR then we would book? I can't find anything specific on the website. Is it too soon to get a positive PCR? None of us have symptoms and all negative LFTs.
