Initiated in 1992, the LABERCA's quality policy was first exclusively focused on analytical testing services. Under constant development, the LABERCA quality assurance system was later (2001) recognised true to the new applicable laboratory standard ISO17025.

In 2004, the LABERCA applied for an audit from the COFRAC to standard ISO17025 with a level 3 flexible range. This new principle of flexible range implies that the laboratory is considered competent to adapt and set up, within the field covered by the standard range, any standardised or assimilated method and develop any other method which it will have had validated. The general range concerning the growth promoters section is the following: "Monitoring of forbidden substances residues of growth promoters-type, corticosteroids, phytoestrogens in food, hair and biological matrices and fluids".

The general range concerning the contaminants section is the following: "Screening of organic contaminants:

• in food or animal feed;
• in beverages;
• in environmental matrices;
• in biological matrices of animal and human origin."

In addition, the LABERCA has initiated a quality validation process of its research activities. The Laboratory progressively turned towards the ISO9001 version 2000 standard and worked on its quality management system in order to bring it up to the requirements of this standard. This considerable work bore fruit in March 2003 when the LABERCA was audited and approved to ISO9001v2000 regarding the management of research projects: design, conducting and valorisation.
