[Metrological problems of laboratory diagnosis].

Medical laboratory diagnosis is progressing from one analysis to a group of analysis with rather intricate statistical processing of data via multidimensional analysis, at the same time it is necessary to define a patient's individual normal levels, i.e. a "health certificate". In this regard, the process may be achieved when complex analyzers, which have a reliable metrological support, and systems for collection of both clinical and laboratory information and its simultaneous analysis are put into laboratories' practical work.
