Reports of RAEMA
The general report
The general dataThis part includes the number of participants, the distribution (in days) of the sending delays of the packages, the level of concentration for each microorganism, the size of the samples, the terms of homogeneity and stability control, the microorganisms that can be enumerated.
Data on analytical techniquesIt includes details concerning the treatment of samples as they are communicated by laboratories, and parameters (such as method, culture medium, preparation, incubation temperature and duration) for each microorganism.
Performance assessmentPerformance assessment is based on the evaluation of the trueness for all RAEMA schemes.
The individual report
Trueness dataFor each microorganism, one page gives the result obtained by the laboratory (in CFU/g and log CFU/g), the z-score and general data on results from all participants for this microorganism (number of laboratories participating to the test, number of laboratories included in the statistical analysis, assigned value for the contamination, standard deviation for proficiency assessment, number of laboratories which obtain satisfactory, questionable and unsatisfactory results). A graphic represents results of all participants; a star symbolizes the result of the concerned laboratory.
Precision dataFor Powder RAEMA, the individual report gives precision data.
Evolution of proficiencyFor Powder RAEMA, data of trueness, precision and qualitative analysis are followed in time. In this way, the laboratory can see the evolution of its performances.
