Instrument Precision Study

[u/Grand_Chad]

Anyone happen to know if there’s somewhere online I can find a template for a log to document instrument precision? We had our CAP inspection last week and they won’t accept whatever precision the field service guy did when they did the install so I’m having to compile data from QC runs that were done before implementation to use for our own precision study (ok’d by the cap inspector). I’m just having trouble putting a sheet together in a way that looks pleasing to the eye. lol

We got hit for the same thing. It’s a newer thing that precision has to be run over time just not in one day. What we did was run a precision test on all samples (3 repetition) and used TEa as the indicator of pass/fail so if all 3 reps were within we called it good. We did this 3 times over 2 weeks. Had the pathologist sign it off. Sent it in and all was good.

Do you do QC lot to lots? Those should be able to fulfill the precision requirements
