BACKGROUND Apart from the wasted resource, canceled tests cause delay of test results thus affecting patient care. The study aimed to identify the reasons for the test cancellation of samples received in a blood bank laboratory and determine the improvement target. METHODS The study retrospectively reviewed the canceled tests in a blood bank laboratory of a hospital in Hail, Saudi Arabia, from January 2017 to December 2020. Records of the canceled test taken from the quality assurance database were utilized to identify the various reasons. RESULTS A total of 2,017 (2.7%) test cancellations were recorded in the 4-year study period with increasing rates noted. The two primary reasons were specimen quality issues (61.9%) and problems related to test orders (33.9%). The main reason for test cancellation was clotted specimen (48.5%) followed by incorrect test order (15.6%) and duplicate test order (13.9%). Statistically, a significant difference exists between the annual rates and reasons of cancellation, X2 (6, n = 2,017) = 83.24, p < 0.001. CONCLUSIONS Test cancellations due to various reasons remain a significant challenge for clinical laboratories. Detailed analyses on these major reasons can aid in displaying an effective approach to decrease the cancellation rates. Harmonization among inter-professional health workers concerning specimen collection and handling, and involving clinical laboratory personnel could minimize laboratory errors and avoid test cancellations.
