Anyone using an External QC with their GEM blood gas analyzers?

The iQM program on the GEMS is Okay, however I am considering introducing an external QC.

I am curious about why you feel the need for external QC. I am asking as a former IL employee who managed clinical trials and did a ton of work in the company's QC lab. I remember this coming up with clients once in a while who were  concerned that their accrediting agencies would not accept the internal QC as part of a "normal" QC program. Just curious really.
