Would be interesting how much resolution they need for the diagnosis to be reliable.<p>Because high resolution mass spectrometers cost millions of dollars, and "minutes" for a diagnosis can mean that one spectrometer can only run 3 samples per hour - or 72 per day.<p>And while a research university can afford a million dollar spectrometer (and the grad students that run it), even a small hospital will create 72 bacterial swaps per hour - while absolutely not having the money to get 10 spectrometers with the corresponding technicians.<p>And the incumbent/competitor - standard bacterial cultures - is cheap!
