1 ANDREW M. CUOMO Governor HOWARD A. ZUCKER, M.D., J.D. Commissioner SALLY DRESLIN, M.S., R.N. Executive Deputy Commissioner Blood ph and Gases Proficiency Test Program Statistical Summary November 2015 (Event 15-3) This statistical report summarizes participant data for the five Blood ph and Gas/Chemistry proficiency survey specimens shipped November 2, Test specimens were commercially prepared and contained carbon dioxide and oxygen balanced with nitrogen in a physiologically buffered matrix. Five specimens (G66, G67, G68, G69, G70) 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. Please note that Glucose, Sodium, Potassium, Chloride, Ionized Calcium, and Lactate, included in this proficiency test event as educational challenges, will be graded beginning with the March 2016 event.
