Yesterday my daughter had a VERY faint positive on a lateral flow that came up after 60 mins. Took her for a PCR which was negative (results received this morning). Have done another LFT this morning to double check and there's the faintest line ever. Like an indent on a pregnancy test. I honestly don't think I'd usually see it but I'm being so eagle eyed. It's her birthday and there's so much riding on it I just don't know what to do! LFTs are from different batches!
