Proficiency tests are important tools to monitor your laboratory and method performance. In 2022 many LactoSens® users have participated in the largest European proficiency test for residual lactose analysis in lactose free milk organized by MUVA Kempten GmbH. About one quarter of overall 38 participants have submitted results using LactoSens® biosensor lactose assay kit. The confidence in LactoSens® was again strengthened by excellent results compared to the gold standard method ion-chromatography.
