I've done it a couple of times and it came out negative. Mrs Urb' works in the care sector and has been doing LFD 3 days a week since the start of 2021 and PCR twice a week since October 2020. Neither Mrs Urb' nor any of her colleagues have ever had a positive result from the LFD tests and they have to show them to the manager when they arrive for work.
Depending on what one chooses to believe, the LFD test either has a v
ery high acuracy of 99% or it's useless and
shouldn't be relied upon. The reality may be somewhere in
between ?
