Lateral flow tests are only meant to be used by people with no symptoms, anyway.
Apart from the results being less reliable than those of a PCR test, the results would also be wide-open to misuse too if they were accepted as 'proof' of being covid-free, because there is no way of knowing if the person claiming it is their result is the person who did the test. I can see many a desperate parent/ grandparent doing this test themselves rather than putting their young charge through the ordeal!
I am dreading my dgd having to do a test.
Before lockdown, she was regularly off nursery with something or other (which she always kindly shared with ds and I), so now she has finally gone back, it is only a matter of time.
I am 100% sure that she would not cooperate with a test ?
