ВЛИЈАНИЕ НА ПРЕАНАЛИТИЧКИ ФАКТОРИ ВРЗ ТОЧНОСТА НА ЛАБОРАТОРИСКИТЕ РЕЗУЛТАТИ
IMPACT OF PREANALYTICAL FACTORS ON THE ACCURACY OF LABORATORY RESULTS

Summary/Abstract: The preanalytical phase represents the most complex and error prone segment of the laboratory diagnostic process. It encompasses all procedures occurring before the analytical measurement itself, including patient preparation, correct sample collection, identification, transport, and storage of biological specimens. Errors during this phase can significantly compromise the accuracy of laboratory results and lead to inappropriate clinical decisions. This paper provides a critical analysis of each step in the preanalytical process, identifies common sources of error, and proposes strategies for their prevention. The aim is to emphasize the importance of standardization, education, and quality control as essential tools for improving patient safety and diagnostic effectiveness
