Verification of instrument after it returns from being serviced (GH100 specifically)

Just wondering what your facilities do when you receive and instrument back from service for a verification. For service on our GH100 instruments we have to ship the instrument to Werfen's tech support depot and once it returns I know we need to verify that it is functioning properly so just looking for what other facilities do for this. We have been running a small precision by running both levels of QC 5 times. Any input is helpful. Thanks!

We do a precision of 5 runs of both levels of QC for whichever tests are performed on that instrument. After that, we run 5 patient parallels between the device that has been repaired and our loaner device. This is usually done in the area where the testing takes place- we give them a worksheet to fill in with the results. All of this is then plotted in EP evaluator.
We don't have these particular devices, but what we do is based on what was serviced/fixed by the company. Sometimes if it is just a battery or power fix, then we just run QC. Likely it is something else, so then in general we would run linearity (if that applies to the analyzer), QC in duplicate over 2 days and 5 patient correlations spanning the AMR. We put everything in EP Evaluator.
I should also clarify that what we do depends on what service was done on the device. If it's anything that has to do with the actual running of the test, then it's the same as I previously described. If it's something like the cord plug replacement, then running QCs is sufficient.
