Background: Pre analytical errors are the main cause of laboratory dysfunctions which compromise the reliability of diagnostic results. These errors occur during the phase before actual sample analysis. Even though this contribute to the maximum proportion of error in laboratory, it is completely preventable. This article is focusing not only on the quantification of preanalytical errors in our laboratory, but also suggests some possible practical remedies that can be adopted to reduce them. Materials and Methods: Current study was retrospective observational study. Total of 29998 samples were collected. Error categories including haemolysis, insufficient quantity, icteric samples and lipemic samples were analysed. The frequency of each error category was calculated. Based on the analysis, relevant remedial measures were proposed. Results: During the 20 months period, out of the total 29998 samples 53 (0.18 %) samples were rejected due to preanalytical errors. Haemolysis (0.067%) was the most commonly observed error, contributing to the highest proportion of rejected samples followed by insufficient sample (0.053%), Highly icteric samples (0.050%), Lipemic samples (0.007%). Conclusion: This retrospective study identified key preanalytical errors and the rejection rate of specimens due to preanalytical error is around 0.18 %. Preanalytical errors can also be taken as an indicator to establish laboratory standards which help to get the best possible laboratory results. Effective management of preanalytical errors require timely monitoring of error sources, implementation of proper corrective and preventive measures and periodic training of laboratory staff.
