1 Blood ph and Gases Proficiency Test Program Blood Gas/Chemistry Educational Proficiency Test Program Statistical Summary November 2014 (Event 14-3) This statistical report summarizes participant data for the five Blood ph and Gas/Chemistry proficiency survey specimens shipped November 3, Test specimens were commercially prepared and contained carbon dioxide and oxygen balanced with nitrogen in a physiologically buffered matrix. Five specimens (G51, G52, G53, G54, G55) were distributed to each participant laboratory for analysis. Results for individual instrument systems where the number of laboratories using those systems is three or greater are provided. Mean and Standard Deviation (± 1 SD) values are calculated by a robust statistical technique that does not assume a Gaussian distribution.
