Article deals with topical issues of quality management of medical services and their implementation in practical activity. For quality of research results, serious problems are created by a lot of objective and subjective factors. To eliminate the problem factors, the course was aimed at developing national standards in the field of laboratory medicine, using international experience that regulate the requirements for the organization of clinical diagnostic laboratories and laboratory analysis facilities. The acute problem of laboratory research is to ensure the accuracy of the results. EC has long been required to provide metrological traceability of calibrators, control materials and metrological provision of laboratory equipment, as well as research methods.
Basic requirement for such research is to provide reliable information to the customers. First of all, it defines the requirement for the quality of clinical and diagnostic laboratories studies, which ensures the correct and timely assignment of a patient's analysis, performed at the appropriate analytical level with the necessary information for interpretation. One way to determine the competence of clinic and diagnostic laboratories and the quality of their research is to conduct an independent quality assessment.
