Prospects of harmonisation of European external quality assessment schemes in occupational and environmental laboratory medicine.
Since 1979, twelve external quality assessment schemes (EQAS) in occupational and environmental laboratory medicine (OELM) have been developed in nine European countries. These schemes cover a broad range of analytes and matrices and have developed differing procedures for the evaluation of laboratories' performances. Collaboration among EQAS in OELM and harmonisation of methods for evaluation of laboratory performance would be advantageous to cope with the demand for assessment of quality of analytical results for an increasing number of analytes and the need to guarantee comparability and consistency of conclusions on health and regulatory issues in different countries and at an international level. This paper compares the different features of the existing EQAS, to highlight critical points for further discussions, and to make some suggestions for possible further collaboration.
