My daughter has been told today she needs to isolate for the next 7 days having had a close contact a week ago. I'm wondering if her school will let her come back before that date if we get a negative test for her. I'm willing to pay to have a private one done as I understand you can only have an nhs one of you have symptoms and she doesn't. There seems to be lots of places online that do private tests but I'm unsure whether to trust them. Does anyone have experience of this?
