[Laboratory staged-programme in diseases of the lung. Aspects and recommendation. (author's transl)]

The dynamic of biochemical processes opened recently an enlarged arsenal of new diagnostic possibilities for the physician. The exponential increase of scientific knowledge led to a progressive increase in the frequency of laboratory analyses. First the laboratories attempted to confront this development by means of rationalization of the structure, organization and analytic factors. Today the laboratories are confronted with a wide-spread polypragmasy, the demand of redundant parameters and irrelevant analyses increases. This contradiction can be solved only by a process of interdisciplinary responsibility. Very important is a change with the result of an improvement of the parameterpalettes leading to a rationalization of the diagnosis. Up to now there is a loch of systematical scientific investigations for the objectiveness and improvement of laboratory parameterpalettes concerning basis diagnosis, differential diagnosis and control of therapy effects in lung diseases. Obviously the cause for this problem in the structure and function of the organ "lung". In this special cases laboratory diagnosis possesses inbordinale relevance. As for the diagnostical process parameters of the function as well as X-ray diagnosis and morphological findings possesses priority. In this study an attempt is made to classify the diagnostically relevant parameters and to force them in a staged system of the medical supervision. With this conception the physician has the possibility to demand laboratory investigations on a scientifically founded basis.
