Comparative interlaboratory tests

Interlaboratory comparison studies measure the analytical quality of laboratories. As national reference laboratory Evira has a task to inform about comparative tests commercially available for the official national laboratories and to ensure an appropriate follow-up of such comparative testing. Evira arranges comparative tests only where commercial reference material is not available. In the Nordic steering group for microbiological reference analysis of food (Swedish National Food Administration, NFA), where Evira is represented, Evira is the communication channel for local laboratories in matters related to reference investigations.
