It only really makes sense if you're going somewhere where they need to make sure you're clear before entry. Ignoring the price issue then it could be used at Oakwell. Take the test at the turnstile and if it's clear in you go, if its positive no entry. At a care home, take the test before being allowed to start a shift or visit a parent.
That's absolutely what needs to happen. Also on the borders before allowing entry into the country. Can you imagine the average pissed up football fan going home quietly though if they get a positive test at the turnstiles?
It would be a nightmare trying to send them home and I'm not really sure how practical it is to test everyone at the ground but it should definitely be done at care homes and like you say at all borders. Its at that point that a lockdown for a month would actually be beneficial as if you can get it down to pretty much nobody in the country and then test everyone entering then you can keep it out.
Care homes are a complete nightmare over here...... https://www.examinerlive.co.uk/news/west-yorkshire-news/7-people-dead-37-more-19169858
limited value. if you absolutely need to make sure you're negative there and then, then fair enough. not sure how many of those circumstances there are likely to be though. and not going to stop you catching it after you've taken it. whatever. it's there if people are happy to shell out for it. I wouldn't. no problem with boots charging for it either. not their responsibility to atone for the government's f.cuk ups
I'm a statistician and you lost me in the second paragraph. I get your point to some extent, but those figures don't add up. A 97% successful test will tell the truth 97% of the time. If you test positive there is a 3% error rate all the time. Your one in 11 thing is wrong, so wrong, to quote Labi Siffre. My workings are 97% of results are accurate. Simple. The more people you test, the more statistically accurate / inaccurate it is.
No - it's right, so right. The odds of you having a false positive test is 3% before you take it. But once you test positive you are more likely to belong to the group of false positives than an accurate positive due to the relatively high rate of false positives compared to the low chance of having the disease in the first place. I'm 100% correct here. Let's say there's a disease which affects 1 in a trillion people. There's a test that's 90% accurate. You get a positive test - do you think it's 90% likely that you've got the disease?
