"(...)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...

> With the tests currently in use, patients must usually wait one to two days for a result.

Is that because it takes 2 days for the test to complete, or because there a 2 day delay from backlog + administrative time?

usually shipping the samples to a lab. this test can be done on the spot in the hospital by a doctor.

The thing is though, the current PCR-based tests can be parallelised, with hundreds being run at the same time, taking just a couple of hours.

The biggest waiting time comes from logistics with transportation to the labs, which is where the Bosch test is advantageous.

"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

That approach makes sense for when you want a low false positive rate, i.e. when the treatment is dangerous or expensive (so you want to avoid it at all costs if it's unnecessary). Here, it's the other way around. Treatment is benign (stay at home unless it becomes an emergency), but a false negative is expensive (you'd infect lots of others). What cheap test do you know that can have a low false negative rate? The only one I know is the one that flags everyone as infected.

How does that help? Which results are you going to treat with low confidence for second pass and why? Positives? Negatives? Both? If both, then what's the point of first pass anyway?

yeah that's bad marketing but who needs marketing these days.

their advantage seems to be that they don't need extra personell to run , so anyone with sufficient safety precautions could use them in a hospital

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