that is a report about one brand of one type of, relatively uncommon, test, which has already been reported as being less accurate.
That's true it's not a PCR, was the only comparison I knew of.
Incidentally the Innova LFT is being used in most NHS Trusts at the moment (according to our Trust emails), and is the one intended for the mass-testing scheme, so it will be the dominant test done by a large margin. It's much less sensitive than a PCR, but it would pick up 40-60% of asymptomatic cases (per test) in any given population which would otherwise not be detected.

It's worth noting that that is a report about one brand of one type of, relatively uncommon, test, which has already been reported as being less accurate.
Here's a study on the method of collection generally: "Patient-collected tongue, nasal, and mid-turbinate swabs for SARS-CoV-2 yield equivalent sensitivity to health care worker collected nasopharyngeal swabs" - https://www.medrxiv.org/content/10.1101/2020.04.01.20050005v1
