French national quality control for pH and blood gases: ten years experience.
A national quality control program for blood gas analysers has been established in France since 1983. Buffer solutions are used at two levels of pH, Po2, Pco2 for testing 950 laboratories using 22 different models. These annual programs inform about the accuracy and the precision of the instruments. They also make the user conscientious to different procedures of quality control. Information is also obtained on the yearly turnover of the types of analysers.
