ABSTRACT
The Quality Management System in medical mycology refers to the systematic monitoring with internal and external quality controls: it needs to be organized in the laboratory. ISO 15189 standard is not precise in how to demonstrate the correctness of tests, in terms of frequency and requirements for quality controls QC. That's why the COFRAC, the French Accreditation Committee has published guides to which we should refer. The laboratory has to apply internal Quality Control Programs. They consist of various tests to check the reagents including the culture media. Reference strains have to be provided and preparations of homemade reagents are needed, because few are commercialized. Maintaining the competence of the technical staff through identification of unknown strains is also required. In the fungal serology field, home made antibodies with pooled sera or antigen controls are needed. This monitoring has to follow the recommandations from the Cofrac technical guide LAB GTA 06. For quantitative analysis, the Levey-Jennings chart is a graph with quality control data plotted on to give a visual indication. Some external QC references, besides the national quality control AFSSAPS, are available. Data evaluation, corrective actions in case of out of range results and preventive actions have to be determined in the Quality System documents and presented in the annual management review.
