Abstract

Introduction: laboratory medicine generates clinical information by analyzing various analytes in body fluids. This process requires trained personnel capable of developing strategies to prevent errors that could compromise patient safety. Recent studies highlight the importance of training and the implementation of protocols to reduce these errors. Objective: to identify available evidence on the contribution of education to correcting preanalytical errors in clinical laboratory testing. Method: a systematic review was conducted using Google Scholar and PubMed, including articles in English, Spanish, and Portuguese published between 2020 and 2024. Only peer-reviewed journal articles were considered. Results: three main thematic categories were identified: Impact of Training in Laboratory Settings, Educational Interventions on Preanalytical Errors, and Methodologies to Reduce Preanalytical Errors Linked to Education. Conclusion: reducing preanalytical errors in the laboratory depends on continuous training and protocol adherence. Initial and ongoing education is key to improving sample quality and patient safety. © 2025; Los autores.
