Dr Muhammad Zubair, Dr Ahmed Raza, Dr Tahir Mahmood

Objective:To find out the leading cause of pre analytical error in a clinical chemistry laboratory. Duration and place: This study was conducted in clinical chemistry laboratory at Chughtai Lab Lahore over a period of 1 year from January 2018 to December 2018. Method:It was a retrospective study which had been carried out to find out the frequency of various factors affecting the preanalytical phase of total laboratory testing. Data were gathered by the help of laboratory technologist who were register data of rejections, and causes for rejections of all the samples which were sent to clinical chemistry laboratory for analysis. Results: Of the 518765 tubes received during the data collection period, 1792 samples were found unsuitable for further processing. This accounted for 0.34% of all samples collected n the laboratory. Rejections arose as a result of the following reasons: 1256(0.24%) specimens had hemolysis ; 147(0.03%) had insufficient sample quantity, 389(0.07%) had compromised or unsatisfactory results. Conclusion: Of all the samples received in the lab, the overall percentage of rejection is 0.34%.
