Aim of the study: Problems of quality and efficiency of health care are among the most pressing social problems of the modern world. The concept of quality of medical services itself differs from the concept of quality of medical care, but both are reflected as a heterogeneous and multi-criteria phenomenon. Currently, both foreign and domestic researchers do not have a single agreed opinion on the content of these concepts, and they are interpreted differently in the definitions of different authors. Methodology: According to the European regional office of the world health organization, quality care should be considered to meet the standards of medical technology, in the absence of complications resulting from treatment, and achieving patient satisfaction. Conclusion: Modern diagnostic methods can be divided into groups depending on the defining feature that underlies the classification. The main role in diagnosis is played by objective methods, among which laboratory and instrumental methods can be distinguished. Laboratory studies reveal problems of the body mainly at the cellular and subcellular levels, while instrumental studies allow us to assess the state of a particular organ or organ system.
