Aim: In this study, it was aimed to determine the causes of preanalytical errors according to the different autoanalyzer and sample types. Material and Method: The rejected biological samples were analyzed in the laboratory information system of Mengucek Gazi Training and Research Hospital between January 1, 2017 and December 31, 2017. According to device types, reasons for rejection and rejection rates were identified. Results: At the indicated dates, 748758 samples were reached in the laboratory, of which 4245 (0.56 %) were rejected. The reasons for rejection are mostly following: incorrect test request (53.6 %) and hemolysis (22.6 %) in the biochemistry samples, inadequate sample (61.5 %) and incorrect test request (30.2 %) in hormone samples, clotted samples (76.9 %) and incorrect sample container (7.9 %) in hemogram samples, level error (38.5 %) and clotted sample (31.3%) In coagulation samples, clotted sample (89.1%) and inadequate sample (5.7 %) in the blood gas samples, incorrect sample container (53.7 %) and incorrect test request (21.1 %) in the nephelometer samples, incorrect sample container (37.4 %) and clotted samples (34.1 %) in the sedimentation samples were identified. Discussion: The preanalytical error sources vary according to the sample types and autoanalyzers. These results should be stated in personnel training and necessary precautions should be taken.
