In this article is described approach of producing of medical diagnostic expert system which based on integration of traditional western and eastern medicines. If necessary, to clarify the probable diagnoses, the doctor should receive from the patient additional information about a human personal condition (medical history, lifestyle, some laboratory tests, etc.). In determining the actual disease present, there arises the actual task of choosing the most preferred atomic diagnostic test (ADT) at each step of the diagnostic process. One of the main directions of this work is research of informativity questionnaire for patients, where such as questions with binary answers Yes or No and questions for determination of human innate nature type. To increase diagnostic precision there has been developed a program method of diagnostic criterion (informativeness) using Bayes procedure and module of analysis based on nominal entropies. One variant of the diagnostic test based on self-assessed health status suggests determining a patient\u2019s constitution due to which it is possible to specify the diagnosis, avoiding diseases that are not typical for a certain constitutional type. Application of the diagnostic model offered motivates a patient to develop a healthy life, adhere to scientifically grounded system of disease prevention, according to the causes of diseases of the given constitution type. Index Terms \u2013 Diagnostic method, health assessment, human innate nature, integrated diagnostic, making decision. I. INTRODUCTION OR TREATMENT, it\u2019s very important to correct determine and to estimate human health condition for make a diagnosis. The traditional western medicine more concentrates on current symptoms of disease. Making diagnosis performs by different medical equipment and accurate methods of research. In the eastern medicine, doctors consider to the human body is a whole system. Human health condition is closely related to the regulation of the basic elements that appears from visualization concepts about mahabodhi (eastern term). At the modern level of knowledge about human innate nature type, scientists believe that it is inherent in all forms of human pathology and the formation of a constitutional risk necessarily precedes the onset of diseases [1]. It is also argued that in pathological processes, the type of constitution significantly determines the boundaries of clinical variability and polymorphism of human diseases manifestations [2]. But the definition of a human innate nature type is a completely subjectively. To elevation of the diagnostic procedures effectiveness should be used approaches which combine the achievements of artificial intelligence, fuzzy mathematics, data mining and etc.,. <\/p>\n","protected":false},"excerpt":{"rendered":"
