title: [The binary ratio method: new possibilities in solution of research and differential diagnosis tasks].
abstract: Binary ratio is the key notion in the general theory of systems, a generalization of functional relationship. A clinical laboratory parameter or sign is merely an element of the analyzed information system, and situations are possible when signs analyzed separately without consideration for their interrelationships are not informative at all, whereas the structure of binary ratio helps solve differential diagnostic problems and other tasks. The information reflected in binary ratios characterizes the relationships between signs and the intricate features in the vital activity of the organism, such as mechanisms of regulation, homeostasis, etc. A method for assessment and comparison of the structure of binary ratios is described as a new method for analysis of biomedical data. The method is realized in a research system OMIS (PC-based) and was tried in the solution of complex problems in hematology, pulmonology, cardiology, oncology, etc.
