Methods: The data is acquired from the Duzce University Medical Application and Research Hospital (DUMARH) laboratories. 5-year (20152019) data was retrospectively reviewed and subjected to document analysis. Results: The rate of the total rejected specimens has increased throughout the years. (2015, 0.88% - 2019, 2.12%). The most prominent rejection reasons are hemolysis specimen (32.9%), insufficient specimen (17.25%), clotted specimen (15.4%) and inaccurate examination request (10.64%). While the reprocessing cost of specimens was 12.085 dollars in 2015, it increased to 51.132 dollars in 2019. It is seen that the rejection rate has increased as the specimen number increased and the reprocessing costs have increased since the inflation in Turkey increased and the purchasing power of the hospital has decreased throughout the years. Conclusion: In order to decrease and prevent the rejected specimen, there is a need for phlebotomy training, especially for nursing and other healthcare professionals, and strict quality control and standard operating procedures for the pre-analytical phase. These are the critical approaches that will improve the service quality of laboratories and patient safety.en10.33808/clinexphealthsci.804238info:eu-repo/semantics/openAccessLaboratory; Rejected Specimen; Reprocessing; Cost AnalysisPreanalytical Errors; Impact; Quality; RatesArticle12167741127939WOS:000782846300010N/A
