Contact tracing has been done away with, why not ask everyone who tests positive on LFT to isolate? What is the point of another test, exposing the staff to the virus etc? The LFT test is not accurate enough to justify ten days of isolation without PCR validation. Quote Link to comment Share on other sites More sharing options...

Because LFTs are unreliable and it's unfair to make someone isolate just because some crap test gets it wrong. Though, as I've said before, I reckon the PCRs must be screwed up as well at the moment, probably due to Lab contamination. 1 1 Quote Link to comment Share on other sites More sharing options...
Raffles Posted July 26, 2021 Share Posted July 26, 2021 My reading is that LFTs are very reliable when they show a positive result, but not so much when showing a negative. Personally I would rather do the isolation than go for a pcr! It would seem to make more sense to ask people to isolate and only go for a pcr if they wish to do so. Rather than telling people to go for pcr, if they get a positive lft result. Quote Link to comment Share on other sites More sharing options...

Anecdotally, my friends have been taking 10 days iso (and checking positive-ness a few times over that period) if they return a positive LFT rather than bothering to wait for an appointment to get PCR tested.

I can see that happening more and more. People aren't going to bother with a PCR plus direction notice and would rather isolate on a LFT, then test through their isolation until they get a negative.

Roger Mexico Posted July 26, 2021 Share Posted July 26, 2021 6 minutes ago, HeliX said: 99.9% specificity for LFT isn't it? No. That's what the propaganda from the company pushing them would have you believe, but the FDA found these to be "false or misleading" and actual issued a recall notice for the test, telling people to "Destroy the tests by placing them in the trash". Rather than the 99% promised, a PHE analysis in April showed that it was only 82% reliable (ie more than one in six positives were false). And of course the real problem is the false negatives. With self-swabbing it's probably less than 60%. It's more accurate than that with symptomatic cases (where people probably wouldn't be going to work/school anyway), but that means it even worse with asymptomatic ones.

BMJ article today - LFT specificity 99.94%, so if it says you’re positive you’re almost certainly positive. It’s sensitivity that is suspect, overall only 40%. So if you’re negative you may be positive! 2 Quote Link to comment Share on other sites More sharing options...
immortalpuppet Posted July 27, 2021 Share Posted July 27, 2021 @BenFairfax - genuinely curious, as you seem to have a very bold statement using your numbers around the future timeline of our current Covid “wave”, has your modelling been accurate to date? Is there a simple graphical format an idiot such as myself could follow depicting your timeline, the factual timeline? Thanks Quote Link to comment Share on other sites More sharing options...

I'm not asking what the family members of people in hospital positive with Covid are doing. I'm asking how a Covid positive person can be discharged if they have no-one to take them home. Pre booked taxi, ambulance, patient transport or family member driving. You really are over thinking. 1 Quote Link to comment Share on other sites More sharing options...

Absolute rubbish https://www.three.fm/news/isle-of-man-news/protect-bin-men-from-virus-plea/ Because apart from covid, there’s literally zero health risk from everything else that people put in the bin. I had a similar conversation with a cleaner worried they could catch covid from cleaning a toilet - presumably before covid they didn’t bother washing hands and were quite happy to generate aerosols while cleaning out the bowl 3 Quote Link to comment Share on other sites More sharing options...

If it comes back positive you are surely at least 99.9% sure to be positive. I think the reason for the PCR is to make it a legal obligation. 1 Quote Link to comment Share on other sites More sharing options...
