Incredible marketing.

#12> Up to 1,000 tests per day on just 100 devices So.. 10 tests per day per device? That doesn't sound THAT impressive.
"(...)the rapid test can detect a SARS-CoV-2 coronavirus infection in patients in under two and a half hours" (...)With the tests currently in use, patients must usually wait one to two days for a result." Well i see here a big improvement...

"under two and a half hours" per test. To be able to make 10 tests per day, you'll probably can't have any delay between tests : 1 day = 10 x (2 hours + 24minutes).
If accuracy is an issue, why not doing a two pass procedure ? 1) test quick and cheap 2) if results have low confidence, move to longer/more reliable testing method

it does, when you take into account the turnover of existing accurate test methods and their accessibility

#15Sounds really impressive, but writing "1,000 tests per day with just 100 devivces" is really marketing BS I think. They should've just written "10 tests per day per device".
Don't current testing machines have much, much higher throughput? Like in the thousands of tests per day? It seems the advantage of this new device is latency. Of course if they are cheap enough and easy to use that you can buy thousands of them and distribute to all hospitals then might also increase total throughput.

The full quote is "A Bosch Vivalytic analyzer can perform up to ten tests in the space of 24 hours. This means it takes just 100 devices to evaluate up to 1,000 tests per day." which makes more sense, the 100 devices is just an example.
But I agree that it's largely unnecessary, the initial "up to ten tests per day" would have been enough.

#17It’s good to see solutions for testing are coming. This test by Singapore a*star nanobiolab can test in 5 minutes : https://www.straitstimes.com/singapore/health/singapore-scie...
Besides comparing times, I guess the accuracies or FP/FN rates are also important. The linked article states 95% accuracy for the Bosch test. Are there any numbers for the 5-minute test?

It’s a really small device as far as I understand, so you could use it in a small practice or even on the go (?). This can be an advantage as most of the lab systems weigh several tons and take up a lot of floor space, hence you can never use them in a decentralized setting.
Re: Bosch develops rapid test for Covid-19
#19It all sounds impressive to me: >In various laboratory tests with SARS-CoV-2, the Bosch test delivered results with an accuracy of over 95 percent. I've read a lot of report on the current tests for SARS-CoV-2 having accuracy issues, does anyone know how 95% accuracy compares to the current methods?
Practicing hospital physician here. We never use the term "accuracy" to describe diagnostic tests, and whenever I see that term used, I'm very suspicious of the claim being made. In other words, this Bosch announcement can probably be ignored.
We use the terms "sensitivity" and "specificity" to describe diagnostic test performance, and never to my knowledge talk about a test's "accuracy." Usually accuracy refers to the sensitivity, but there's a lot of liberty taken with that term in marketing talk.
For example, the existing PCR test being used does not have ideal sensitivity, which for practical purposes means that there is a substantial false-negative rate. Which is why (among other reasons) we weren't testing asymptomatic patients in the early phase.

True. This is seems to be on one of the extreme ends of latency versus throughput optimization and its niche in the big picture of Covid-19 will be very small.
But it appears to be a new test cartridge for an already deployed machine, so it makes sense to have it anyways. I don't know who the typical customer of an on-site lab in a box like that is, but I guess that as last part of the market will be defined by remoteness and there it absolutely makes sense.
