Am I missing something? The Roche website says
Designed to provide a fully integrated real-time PCR workflow,
the cobas® 8800 system can run up to 960 tests in an eight-hour
shift with minimal user interactions and up to four hours of
walk-away time per run when running at maximum capacity.
(24 / 8) * 960 = 2,880 per day
Update: formatting
- mlyle 7y agoIt looks like that the 960 number is predicated upon a start time from "idle", and minimal interactions. The actual slope rate of test completion looks like it's 192/hour. If that throughput can be maintained with more frequent interaction to keep the machine fed, it'd be 4.6k/day. https://www.dialog.roche.com/content/dam/dialog/owp/apac/Media/Molecular/cobas-8800-performance.png https://www.dialog.roche.com/content/dam/dialog/owp/apac/Med... That is, it takes time to "stuff the pipeline". The cited number -- 4128 -- appears to be 21.5 * 192.
- maxerickson 7y agoI think the sample handling part is faster than the PCR part, but you might have more than 1 PCR part setup on the machine. So if that is true, it isn't labs multiplied by the PCR rate to get to a testing rate, it's the sum of the bottlenecks of the installations.
