I am assuming they are the lateral flow tests which tend to miss quite a big amount of positive cases?

Lateral Flow Tests missing a large number of positive cases is not necessarily negative.

Lateral flow tests and PCR tests are very different tools for very different scenarios. PCR are good to spot that you have had the virus, but will still return positive long after you are no longer infectious. Lateral Flow Tests are a better indicator of infectiousness.

I've found some of the stuff Tom Chivers, and Tim Harford have written on this subject very informative

All true but not really relevant to what I wrote, the bit you quoted was originally written by gms not me.

Yes, sorry I realised that and tried to edit it, but can't seem to change the reply to without deleting and re-posting, you've shown me up as being too lazy to fix my mistakes.
