    Testing capacity in Germany will be increased by up to factor 10 to up to 400,000 a day (!) by doing pooled testing. E.g mix 16 samples and if negative - all are negative, otherwise binary search for the positve(s). Could of course be used worldwide.https://twitter.com/CiesekSandra/status/1244663632815968257 …

        since many are asking: the article did not provide details about the exact method. In the article, they talked only about pools of 5 but that would not allow a 10x scale factor. So I assumed pools of 16 in my Tweet. Maybe @CiesekSandra can share more details.

        I guess the "pooling strategy" is important for the scale factor. I live in a household of 4. If we would test we would not even really care who tested positive since we then would assume we all get it anyway. So it is all or none anyway.

        The article introduces a new *patented* method for pooling (which is not that novel IMHO) and hopes they can sell their patented „invention“. It doesn’t say that this method will be rolled out in Germany AFAICS.

        Damn. That is smart and no brainer. Has this been applied to the med testing field before?

        Multiplex PCR is common, not sure this much testing has been done at such scale so probably not been needed before.

        Interesting indeed. But to find 1 positive in 16 requires 9 tests, so I guess the 10x improvement comes from testing a lots of negative batches. Also, how easily can the swab create batches that can be expanded to 5 samples?

        Where did you get 9 from? I make it 4 with a binary search? But maybe my maths is bad?

        Dutch are aiming at.. 29k by 1 week. Presently they are at 4k a day. Now check the #NL stats (3th in mortality rate per capita after Italy & Spain😔). Then you'll see why testing is so important..
