Sažetak
Quality assurance of the analytical results is obligation of all analytical laboratories which tends to be credible. In order to obtain accuracy and precision of results each laboratory implements suitable programmes according to EN ISO/IEC 17025:2006. Since 2005, Reference Laboratory of Dairy Science Department is accredited according to mentioned norm. Validation of analytical methods and verification of validation parameters are part of good laboratory practice. Quality of analytical results is assured by use of certified calibration standards and by participation in international proficiency trials which are organized by dairy laboratories from Germany, Italy, France, Switzerland and Slovenia. Reference Laboratory of Dairy Science Department has its own protocol of quality control which is based on analytical procedures and methods which are traceable, accurate, reliable and applicable for certain purpose. At the same time, our laboratory organizes proficiency testing for other dairy laboratories. Results of analyses are statistically tested and on the bases of z score, slope and intercept of regression curve, we estimate the successfulness of measurements (Fig 1.)
