Interlaboratory comparison studies measure the analytical quality of laboratories. As national reference laboratory Finnish Food Authority 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.
Finnish Food Authority 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 Agency, NFA), where Finnish Food Authority is represented, Finnish Food Authority is the communication channel for local laboratories in matters related to reference investigations.
