The scene of clinical biological analysis is continuously changing in the face of the demand for even more powerful tests for in vitro diagnostics. To ensure the reliability of results, National External Quality Assessment Schemes (NEQAS) have been established in several European countries. In order to comprehend the different ways in which European EQAS for clinical biology are functioning, the Community Bureau of Reference organised an inquiry in 1989, focussing in the first instance on hormonology. The inquiry involved the following items: - type of substances submitted to NEQAS - organisational aspects relative to participation in NEQAS (such as number of participants, anonymity) - funding of schemes - materials and methods including: type of samples, number and frequency of surveys, interpretation of the results, definition and use of "target values", criteria for assessing the performance and consequences for the "poor" performer.
