DC had contact with covid positive child at the weekend. Last evening, she produced the test below (no line after ten or so minutes but this morning, it looked like this...). Did another which was negative (more confused than before...). What do you think? Might take her for a PCR, am undecided (we're not in UK in case you comment she does not need to isolate any more under government rules ;-))... She is asymptomatic and has not had Covid yet and is not vaccinated.
