Faint positive LFT then negative test later

[ArianaG]

Has anyone experienced this?

I tested positive with a faint line on an LFT yesterday then to check I did a further test a few hours later and it was negative.
Very confusing.
Going to test again today.

Asymptomatic so don't need a PCR.

Yes my nephew had this over Christmas. Faint negative 1 day, then a negative later, then another faint positive next day (infection later confirmed by pcr).

My advice would be to not go visit your elderly grandparents right now.

You can get a PCR to confirm a lateral flow ( although who knows for how much longer). It could be the start ( or end depending how often you test) of an infection but my DS sometimes gets false positives on one brand of tests. I've taken to just repeating the test a few hours later as it was cruel to have him keep missing school while waiting for a PCR ( or better still just use a different brand of test).

Yes, this happened with DH. He got a PCR as he wanted to be sure, as he really couldn't afford to be off work at the time, and his PCR was negative.

Thanks for the replies everyone. LFT negative today.
