The technology below can do it in 15 seconds. An ingenious 18 year old glucoses meter company hacked a glucose meter to do it. Interesting past between them and JNJ. They submitted it for EAU. http://www.pharmatechsolutions.co/assets/inserts/20200318_GenViro!_PP.pdf http://www.pharmatechsolutions.co/assets/inserts/20200318_Ge...

I was super impressed by this 18 year old, but the company is 18 years old. https://finance.yahoo.com/news/decn-finalizes-fda-pre-eua-141500114.html https://finance.yahoo.com/news/decn-finalizes-fda-pre-eua-14... Looks like this is a Korean developed test. Pretty cool.

Until it gets proven and FDA approved, I'd be skeptical. Not saying it's not possible though. Spain, Prague and Italy received tests which were 80% false so we don't want that to happen again.

  I promise I’m not being a smart ass, but can you point me to a reputable source for the 80% false claim? I’ve seen a lot of people complaining of inaccurate tests, but have not come across any news articles myself. Maybe just for lack of trying :) I ask because I saw articles about rapid tests (a few hours for a result) claiming accuracy of 98% plus in South Korea. I’m not saying the info isn’t out there, I just haven’t seen it, there is too much crap flying around.

      It looks like the problem isn’t with the tests, but rather they are buying uncertified products. From the first link, > the company that made the test kits, Shenzhen Bioeasy Biotechnology, had not been on Beijing’s list of certified providers > Spanish health officials said they bought the tests from an unnamed third-party distributor Furthermore, the Spanish health officials used the test wrong, > In a statement on social media, Bioeasy said that Spanish officials did not understand how to conduct the test and that it made videos and issued instructions to help them.

That's a Serological test and it only goes positive about 5 days from infection, by which time you're probably not that contagious. This is a nucleic acid test which directly detects the virus and will be positive if you're contagious. They're complementary, but you need a molecular test to stop the spread. This will be a very good product.

  would this tell you if you had the virus in the past and therefore have built immunities?
  - JonathanFly 7y ago
    Yes, serology tests are antibody tests.
  - jrockway 7y ago
    I think you need an antibody test for that, which apparently you can buy for $20 starting on 4/1 (there was an article about it on HN this week).
- quietbritishjim 7y ago
  I have also read that it takes between 7 and 14 days from infection until you start to show symptoms. From your comment that would mean that anyone showing symptoms is "probably not that contagious". Given the exclusion rules rules here in the UK that doesn't sound right. What piece is missing?

    The onset of symptoms starts between 2 and 14 days after infection with 3 to 6 days being the average depending on the cohort. [1] Outliers exist, such as one patient that did not show symptoms for 27 days. It is unknown when a person becomes infectious, but so far data suggests that its days before symptoms appear for most patients and as many as two thirds may be completely asymptomatic.
