Abstract : Background: Pre-analytical errors remain the leading source of laboratory testing failures and significantly influence patient safety, cost, and turnaround time. Specimen rejection rate is a recognized laboratory quality indicator.  Methods: A retrospective analytical study evaluated all rejected specimens received between January and December 2024. Rejection rates were calculated using total test volumes. Statistical methods included descriptive statistics, binomial confidence intervals, chi-square testing, coefficient of variation, time-series analysis, Pareto analysis, statistical process control (p-chart), and performance benchmarking.
