External quality assessment bodies use a coding system to identify the techniques used in the analytical phase of each examination. Where quality control of a medical biology examination is carried out by more than one body, these bodies use a common coding system.
The Agence nationale de sécurité du médicament et des produits de santé coordinates the production and updating of this coding.
An order of the Minister for Health sets the criteria and limits of acceptability for quality control of the results of the medical biology examinations mentioned in Article L. 6221-9. This order may define the minimum number of annual participations. It is issued and amended after consultation of the committee referred to in article L. 6213-12.
