Had an email today from our nursery to say my son has to self isolate due to a child testing positive. Said child attended nursery yesterday. So he/she would have had to have had been tested at a centre (as post test wouldn't have arrived in time). My daughter had to have one earlier this week, so I know the earliest time bookable is 8am. Nursery emailed us at 4pm. My daughter's (negative test) came back on Tuesday in 18 hours, which I thought was super quick. It seems very fishy to me that the child could have been tested/results returned/contacted nursery/nursery emailed parents, within 8 hours. Or am I being unfair and the tests really can be that quick? I know noone can help being sick. I'd be livid to think a parent sent their child in on Friday waiting a test result though.
