The material presented in this publication was originally prepared for the Cornett-Assess project, a program to develop health technology assessment activities with industrial organisations in Europe, which was supported by the European Community. The case study evolved as an approach to a self-guided instruction course on the assessment of a particular area of diagnostic technology. It has been issued as a working paper in view of continuing interest in non-laboratory pathology testing. The diagrams prepared for the self instruction course have been included in an appendix.
A shortened version of this material, together with chapters by contributors to the Cornett-Assess project on a number of other topics, will appear in Assessment of Health Care Technologies: Case Studies, Key Concepts and Strategic Issues (A. Szczepura and J. Kankaanpaa, Eds), to be published by John Wiley, London, during 1995.
