Contrôles internes et externes de qualité pour les techniques Elisa de sérodiagnostic aspergillaire : propositions du groupe « sérodiagnostic fongique » de la Société française de mycologie médicale [Internal and external quality controls for Elisa techniques of aspergillosis serodiagnosis: proposals of the group "sérodiagnostic fongique" of the Société française de mycologie médicale].
Résumé
In the end of May 2012, a meeting of the group "sérodiagnostic fongique" of the "Société française de mycologie médicale" had concerned quality controls to use, in particular, in the follow-up of Elisa techniques. A preliminary investigation showed that the internal quality controls (CIQ), according to the terms defined by the accreditation, were not systematically used. In June, was published the new guide of the COFRAC SH-GTA-06 on quality controls, this text being applicable on July 1st, 2012. It incited the working group to formulate proposals on the choice of the CIQ for antigen and antibody Elisa in the aspergillosis serodiagnosis. Informations on the external evaluations of the quality (EEQ) have also been given to better define for what we can expect from it. All these controls will allow every laboratory to better master the used techniques and their conditions of realization. A strengthened dialogue between the users and the manufacturers should incite these last actors to improve the supplied kits. It will drive later to an improvement of the reliability of the results obtained by these techniques and their interest in the aspergillosis diagnosis.
