Do you trust a negative PCR over a positive LFT?

Person tests positive on LFT - people are notified and told to isolate then contacted again to say they don't have to isolate as PCR is negative.

I know the stance is that the PCR is the one to be believed, but from a personal POV would you trust that result? Would you be happy to crack on as normal, visiting vulnerable relatives etc? Or would you err on the side of extreme caution?

Previously I would have accepted the PCR but I would have still avoided my mum who's on chemo for the 10 days and avoided cafes etc.

But since the cock up in the medical facility resulting in 40k false negative PCR tests (and my school was involved in that and we believe some were false neg pcr due to the continued and prolonged spread) I wouldn't trust it 100%.

Couldn't isolate because work wouldn't allow it but I'd switch to online food ordering etc.

Trust the LFT. Especially if there was more than one positive LFT.
I had multiple very dark lft over 9 days. Unmistakable positive. Yet 2x pcr were negative before I finally got a positive on a postal test. It is probable that my 2x negatives went to thr dodgy immensa lab as I subsequently got a text telling me the results may be wrong (even tho I'd had my postal positive by then).
Luckily I stayed in because I had read enough on twitter to know there was something funny going on, but I could have infected so many people if I'd believed the PCR.

We've had multiple positive LFT's/some symptoms/negative PCR and multiple negative LFT's/no symptoms/Positive PCR for one member of the family so I no longer have much faith in any of the tests.

@PoppityBoo and others - I would bin the tests after the set time - that time is what they were trialled on. Test regularly, set the timer, look hard, bin. An LFD that is positive within the set time is very, very likely to be a true positive.
