epoc TCO2 linearity validation

Hi All,

We are in the middle of our epoc validation and have come across a problem with TCO2 specifically. Our reportable range is 10-50 but the calibration material the vendor used while on site to validate only went from about 6.5-30.

Am I Overdoing It with my CAP Quality Cross Checks

I would like to get some advice.

We have two (2) GEM 7000 in the main lab and also four (4) GEMs at the point of care.

I initially ordered the CAP Quality Cross solely for the instrument to instrument comparison but it has become a hassle to ask the end users to run it on the instrument. Quality cross checks has 3 pairs.

I was thinking...
