QUALITY CONTROL IN THE CLINICAL ANALYSIS LABORATORY IN THE ANALYTICAL PHASE: SAFETY OF RESULTS

Abstract

Clinical analysis laboratories assist in medical decisions, and for this, doctors and patients need to have confidence and security in the reports provided by these laboratories. The present work is a research, which aimed to search for articles that describe the importance of the clinical analysis laboratory and its problems, as well as the means of quality control of these companies.For data collection, the SciELO databases were used. The analyzes showed that, currently, the search for quality is a priority when choosing the services of a clinical laboratory, given the importance of the laboratory test for the doctor's decision-making. In this way, numerous questions were raised regarding the level of quality of services provided by a clinical laboratory in its various stages, and which led to the emergence of programs such as PELM, DIQC and PALC, with the aim of obtaining a form of certify the quality of the laboratory. The data presented allows us to conclude that quality control programs define the clinical laboratory with a high degree of excellence in its activities, being a differentiator in the choice made by users of the service provided.The quality control phases include pre-analytical, analytical and post-analytical processes. All laboratory activities must be documented through Work Instructions (IT) or Standard Operating Procedures (SOP), approved and made available to technical and support staff. Laboratory quality control can be divided into two categories: internal or intralaboratory quality control and external or interlaboratory quality control. Therefore, for the efficient installation and organization of a quality control program, procedures must be implemented and improved, including continuous professional technical training, awareness and commitment of each professional and management team.
