For the lateral flow testing kits (same swab method, but different test to PCR), the BMJ found that the sensitivity (True positive rate) dropped from 73% with healthcare staff to 58% with members of the public.
The evaluation found that the test performed best when used by laboratory scientists when the sensitivity was 79% (156/197 positive: 79.2% (95% confidence interval 72.8% to 84.6%)).
Sensitivity dropped to 73% when used by trained healthcare staff (92/126 positive: 73.0% (64.3% to 80.5%)) and to 58% with self-trained members of the public (214/372 positive: 57.5% (52.3% to 62.6%)).

PCR test have a much higher sensitivity to start with but presumably there will be a similar drop off due to a relatively poorer swabbing technique by the self-trained public.

Like Daniel Hannan's article where he said Hoxton will become the new silicon valley.

It's in Waitrose if you're curious.

I've been trying the Hoffman promoted 'Mylk' the past few days.
Awful. It curdles very easily, is dominant in taste and has quite a strong coconut smell.
Pretty much any oat milk, barista or otherwise is better.

The west is much harder hit by the virus, partly because of demographics, so they are the most in need.
Although Italy, who have now overtaken the UK in Europe for highest deaths, have barely got got a vaccination plan together.

Like giles I can't give a specific recommendation, I got my Kef R100s largely because they were a good price, but I've been interested in some DIY kits for the LS3/5a BBC model speaker design, e.g.:

It seems like a cheaper funner way to get ~£1000 performance speakers, but I've not looked into it much for fear of actually doing it!

We're not burning red tape, we're just covering it in blue tape.

Finally finished welding my speaker stands. Sanding and painting next. I copied the Something Solid XL design.

On a more serious note, skiing is fairly socially distanced to within your friends and family group
Alpine ski resorts were basically the warm meat market of Europe. They were the sites of the biggest outbreaks in Feb/March and are directly linked to the initial outbreaks in dozens of countries. The Austrian resort, Ischgl, is linked to cases in 45 countries alone.
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.
