I'm not sure if there is any reliable official data,maybe with good reason? I think there was some research published back in March that pointed to roughly 70% reliability,of course that wouldn't include the delta variant,which seems to have caused the recent spike.
From the Pharmaceutical Journal... A Cochrane review, published on 24 March 2021, investigated whether commercially available, rapid point‐of‐care antigen (lateral flow) and molecular tests were accurate enough to diagnose COVID‐19 infection reliably, and to find out if accuracy differed in people with and without symptoms. The reviewers included 64 studies published up to September 2020, which investigated 16 different antigen tests and five different molecular tests. They found that in people with confirmed COVID‐19, antigen tests correctly identified COVID‐19 infection in an average of 72% (ranging from 34% to 88%) of people with symptoms, compared with 58% of people without symptoms. In addition, they found that the tests were most accurate when used in the first week after symptoms developed. In people who did not have COVID‐19, antigen tests correctly ruled out infection in 99.5% of people with COVID-19-like symptoms and 98.9% of people without symptoms.
Has any of you with the relevant experience got any revision tips for people before they take the tests?
Over 18 and still need your first jab? See info below for Walk-ins at the Alf Marshall Centre, Bransholme every Wednesday 9 am - 5 pm during July. Over 18s are invited to #GrabaJab today at the Dennison Centre @UniOfHull No appointment needed - both 1st and 2nd doses of Pfizer and AstraZeneca available Remember you must have had your first dose at least 56 days ago in order to receive your second dose. https://twitter.com/NHSHullCCG

Wow. A range of 34% to 88%! So, some LFT's that people are using have pretty much a 1 in 3 chance of being accurate!! With the average being 2 out of 3 (meaning half of all LFT's have less than 2 out of 3 accuracy). That's pretty poor. Rolling a dice and having odd number = positive, even number = negative is just about as effective and a lot cheaper, (subject to inflated prices for dices (spl.?) given the global shortage that would ensue).
No appointment needed: pop-up vaccination clinics come to Hull. There will also be free, fast, no-symptom tests available on-site, as well as test kits to take home. The first will be held this week in Peel Street Park, close to the north end of Springbank, on July 7-10, 9am-6pm. Future dates and locations are below. Please note, these could be subject to slight change. The council website will be updated in-line with any amendments: Constable St Playing Field, Wednesday July 14 – Friday July 16, 9am-6pm Tranmere Close, Wednesday July 21 – Friday July 23, 9am-6pm Beverley Road area, further details TBC Two further sites, TBC. https://www.hullccnews.co.uk/05/07/...eded-pop-up-vaccination-clinics-come-to-hull/
City Hall are taking walk ins for jabs starting from Monday 9-6 apparently As well as the mobile ones too
Went to see the Tony O'Malley band last night. It was fantastic hearing live music in a regular, indoor venue. A real uplifting experience. **** covid!
Doesn't really matter though does it. Even at the lower level if you tested twice a week you'd be 66% likely to find it even without symptoms, and regardless the tests give you an infinitely better chance of finding it asymptomatically then not getting tested at all. You'd paid your share of the £37Billion to Dido to buy them so why not use them? They're extremely unlikely to say you have got it if you haven't (1/100), and at least a 1/3 chance of finding it if you do. Sensible odds to me considering you've already paid for them.
Of course not all lateral flow tests are useless - recently published results for the UK-RTC AbC-19 Rapid Test lateral flow immunoassay (LFIA) have proven to be very reliable (BMJ). Sadly we're not using that. John Deeks, lead author of the Cochrane report mentioned by OLM, is scathing in his criticism of the Innova tests. His own impromptu study of self testing students at Birmingham University showed a test sensitivity of only 3 per cent. So, using DBT's logic you might expect to get a correct positive result in 33 or so tests if you collect your own sample at home. When it comes to vaccination we've focused on several reliable, tried and tested manufacturers but for testing we've abandoned the AZs/Pfizer's and put all of our faith in the Arthur Daleys of medical technology. The moral is, if you have to kiss frogs in search of a prince (or princess), choose your frogs with care.
Assuming the "Trace" system works, every false positive results in a group of people isolating unnecessarily. At the same time, a whole load of infected people, who should isolate, are wandering around undetected, infecting other people. I have no problem with rapid tests per se, but this particular version is not fit for purpose.
