Nope. She said he has symptoms, so he does have to isolate whilst awaiting results. Not sure if either of them are jabbed, but if not then they have to isolate also if it comes back positive.

Had the same with my son he tested positive on his 13th birthday yesterday but I’m not an idiot and have stayed in lol
