[Liver diagnostics].

Abstract

Prerequisite of a scientific and rational liver diagnostics is the knowledge of the physician of function and structure of the liver. The laboratory demand should always be an accomplishment of the physician and should be performed only upon such a scale that it is also followed by therapeutic consequences and/or consequences concerning the expert's opinion. The biochemical blood analysis gives information about the size of the injury to the parenchyma and about the disturbance of the various partial functions of the liver. In this case is to be taken into consideration that biochemical and histological parameters are no concurrent, but supplementing diagnostic methods. A progress in liver diagnostics is the use of the isoenzymes of the aspartate aminotransferase and the lactate dehydrogenase as well as of the enzymes of the metabolism of the connective tissue. With the entering into selected parameters of the liver diagnostics possibilities to the establishment of the disturbed liver metabolism by means of markers are shown and at the same time recommendations for the praxis of the liver diagnostics are derived.
