[Critical study of the interpretation and use of laboratory biochemical examinations in a hospital milieu].

The criticism of interpretation of routine biochemical examinations by four clinical units (motor rehabilitation, cardiology, gastro-enterology, diabetes) was in relation to four criteria: result in agreement with the clinical observation but not providing new information, result in disagreement with the clinical observation and judged too low, result in disagreement with the clinical observation and judged too high. The comparison of judgements with regard to various analysis permits one to discuss applications of a method of objective assessment of the dialogue between the laboratory and the clinical units.
