The major cause with false negatives is that people don't swab correctly.
But that is neither here nor there stay safe old person snigger.
EDIT:snogger is auto corrected to snigger.

It’s certainly an issue with the dichotomous lateral flow tests which only read out yay or nay, and don’t indicate if a swab was sufficiently swabbed (eg, by testing for the presence of a related enzyme). The study I’m thinking of was done in Canada on samples taken at a regional hospital, iirc. That’s not to discount human error entirely, but the likelihood is lower. It’s not the only study indicating that available testing methods aren’t unerring (NY did a massive study but I don’t recall if it was for PCR tests).

My and the husband feel old so the no snogging old people bit is going to be tricky ;P
Wow 9% false negative? We have no symptoms of disease but will keep an eye out, we always wear a mask and I have a box of LF tests.
The Christmas work do is in 3 weeks...if there's any doubt I will get a PCR test. Because it's all inside... :(
