Emerging research suggests saliva-based PCR tests may offer the earliest opportunity to detect omicron. However, early studies offer a more messy picture for at-home rapid antigen tests.
so the result is negative. can i just say this test says i m negative and the lateral flow i did today says the same thing. tests like these seem very impressive, and if they work, they could really help to get things moving again. but the scientific community is still divided on whether saliva tests are effective enough to be used to detect covid. and previous tests which have been announced with much fanfare have been swiftly muted. in may, british airways announced trials of an ambitious 25 second covid saliva test, described as a game changer by its ceo. but six months later, the test is still not available in the eu and has not been authorised by the fda. the advent of testing and vaccines has changed how we think about living with covid, and improving the testing experience further with technology like this might make it easier to control the virus. we just have to wait to see
we ve been waiting for this for 20 years and, you know, here it is. like anything to do with crypto and blockchain, there is a huge buyer beware to getting involved. some initiatives are legitimate, but others are scams, and sometimes, it can be very hard to tell the difference. treedao says that what it s doing shows how this new way of running things could be used responsibly and effectively. but it s early days for these ideas, so what daos really end up being used for could surprise us all. depending where you are in the world, whenever you enter a building or an event, you might be asked to do a rapid antigen test, a lateral flow test. now, the thing is these can take 15 minutes or more to do. but over here, i ve got a test that is gone in 60 seconds. this is patrick von den bogaard. patrick, welcome. thank you. what i have to do to
do your 60 second test, then? first, i will give you a swab and ask you to let saliva pool underneath your tongue. and when that is done, you can put this in the pool and let it soak for about 15 seconds. this test is doubly unusual because it only uses saliva. it s no surprise, really, that quite a few people across the world are trying to develop an accurate and effective saliva based test one doesn t require nostril probing or gag inducing throat swabs. the super fast result here is achieved using nanotechnology. the idea is that by forcing a small amount of saliva into a tiny sensor that confined molecules in the saliva, react with each other and create a readable solution much faster. the results can be analysed by a microscope in the machine. ok, well, this has been cooking for more than a minute. it says it s complete, so let s see what the result is.
