Abstract
|
|
|
|
In the 2016 and 2017 programs for blood gas analysis (BGA) in central laboratory and by point-of-care testing (POCT), and glucose analysis by POCT, external quality assessment of 9, 3, and 1 analytes, respectively, was performed each year. The materials used were commercially available quality control materials, and three levels were used per trial. Based on the information and results from each participating laboratory, statistical analysis was carried out. Results were provided to each laboratory through individual and comprehensive reports. The mean response rates were 96.6%, 96.5%, and 95.6% for BGA in central laboratory, BGA (POCT), and glucose (POCT), respectively. The number of participating laboratories in BGA (central laboratory and POCT) in 2017 was not significantly different from that in 2016. However, in the glucose (POCT) program, the number of registered instruments sharply increased in 2017 as the allowable number of registered instruments was increased from 5 to 30. The coefficient of variation (CV) did not show any significant differences in pH, sodium, chloride, and ionized calcium of BGA. However, the differences of CV were found to be relative large between instruments in other analytes of BGA and glucose POCT.
