Abstract
Quality Control (QC) and Good Laboratory Practice regulate the organization, performance and conditions under which tests are performed, registered and released, how biological materials are conserved and disposed of, and results archived. Mostly, the pre-analytical, analytical and post-analytical phases are included in QC. The clinical analysis laboratory is divided into sectors, and in the microbiology sector, the urine culture test known as another standard for diagnosing urinary tract infections (UTI) is carried out, which constitute one of the most constant clinical conditions among human infections, covering several syndromes, recognized by the presence of microorganisms in the urinary tract and because they are often followed by an acute and symptomatic inflammatory response. Observing the importance of quality control in the microbiology sector, this study aimed to evaluate QC practices related to urine samples and urine culture in clinical analysis laboratories in the Alto Vale do Rio do Peixe region in the state of Santa Catarina. Data were obtained through open and closed questions made available to the laboratories via Google forms. Fifteen laboratories were evaluated, of which 11 reported fulfilling 73.4% of the activities within good laboratory practices. Of the laboratories that have collection points, 2 carry out 40% of the practices consistently. According to the results and bibliographical research, it was found that the insertion of Quality Control guarantees a safe health service, and may reduce unnecessary medical prescription, and may even reduce costs to laboratories.
