Introduction: Sometimes, laboratory diagnosis accompany by errors. Detection of these errors could be effective in preventing their occurrence. This study aimed to evaluate random errors and their causes in a Hamadan teaching hospital laboratory during the years of 2020 to 2021.
Methods and Materials: In this cross-sectional and retrospective study, recorded random errors in a Hamadan teaching hospital laboratory was gathered during 2020 to 2021. The data were analyzed by SPSS software version 24. Frequency and percentage of desired variables were presented.
Results: According to the results, 312 random errors had been recorded. 98 (31.42%) of them had been only detected by Westgard method and 214 (68.58%) had been detected by both of Westgard and WHO methods. 98 (31.42%) of the random errors had been detected by R4S Westgard rule and 214 (68.58%) of them had been detected by 13S Westgard and WHO rule. The most common causes of random errors were equipment failure (109, 34.93%), reagent failure (82, 26.30%), environmental factors (68, 21.79%) and human error or procedure change (54, 17.07%) respectively. The most errors were related to biochemistry 200 (64.10%), hematology 70 (22.43%) and coagulation department 42 (13.47%) respectively.
Discussion and Conclusion: The main causes of random errors were equipment and reagent failure. Equipment update, reagent quality control and staff training could be effective in the reduction of these errors.
