Jody Posted October 15, 2013 Share Posted October 15, 2013 For those of you that make PBS:How are you testing the ph? If your response is ph paper, what are you using for QC?Thanks! Link to comment Share on other sites More sharing options...
cthherbal ☆ Posted October 16, 2013 Share Posted October 16, 2013 We buy 3 pH buffer standards from our distributor (cheap)- low normal and high. We test the 3 buffers monthly along with our saline on pH paper. This works out well and we've had no issues. Link to comment Share on other sites More sharing options...
Trudy14 Posted October 18, 2013 Share Posted October 18, 2013 This may be obvious but what is PBS? Link to comment Share on other sites More sharing options...

bbbirder Posted November 11, 2013 Share Posted November 11, 2013 We are next to hematology, so we borrow some of their urinalysis controls to QC pH paper. However, most of the time we QC the saline on a blood gas analyzer. They run QC regularly anyway. Link to comment Share on other sites More sharing options...
QCDan Posted November 13, 2013 Share Posted November 13, 2013 and this is in reference to what standard ? help please. Link to comment Share on other sites More sharing options...
bbbirder Posted November 14, 2013 Share Posted November 14, 2013 We do pH testing on the PBS because the manufacturer requires it for our Echo analyzer. I don't know if that is why others do it or not. and this is in reference to what standard ? help please. Link to comment Share on other sites More sharing options...
QCDan Posted November 15, 2013 Share Posted November 15, 2013 We test the pH also for our instrument, I have the certificate of analysis for the pH paper but we do not do QC on the paper. if we would start to have results out of the norm I would perform testing on the pH paper as part of troubleshooting. I was trying to find out if there is a standard (AABB, CAP, or otherwise), that states that pH paper needs to be quality controled. Link to comment Share on other sites More sharing options...
roberman Posted November 15, 2013 Share Posted November 15, 2013 We test it on our blood gas analyzer. Link to comment Share on other sites More sharing options...
cthherbal ☆ Posted November 15, 2013 Share Posted November 15, 2013 My thought is just that we QC all reagents used for patient testing. Saline is a reagent, so it gets QC'd. pH paper is also a reagent. Link to comment Share on other sites More sharing options...
