Although, Ethiopia is working to improve the qualities of laboratory services, errors are still prevailing. These errors are classified as pre-analytical, analytical and post-analytical. Studies that focus on prevalence and factors that influence the pattern of laboratory error remain very scarce in Ethiopia. This study aimed to assess the extent of pre-analytical error and factors contributing to this error among blood specimens referred for CD4 and Haematology tests. We conducted a quantitative study triangulated by qualitative technique in three laboratories in Central Oromiya; Ethiopia. For quantitative study, a total of 754 randomly selected blood specimens and its accompanying laboratory request forms were reviewed using a structured checklist. Data was analysed using SPSS version 20 software. P value of less than 0.05 was considered as statistically significant. For qualitative part thematic content analysis of the interviews was performed using Open Code software version 3.4 and three different categories were emerged. The magnitude of pre-analytical error among 754 blood specimens and its accompanying laboratory request forms was 314 (41.6%) with 95% CI of (38.3-45.2). Blood specimen collected using syringe and needle methods and specimens collected in under 15 years old patients were prevalent for pre-analytical error; with ORs (95% CIs) of 4.948 (1.993-12.285) and 6.973 (4.032-12.060) respectively. In-depth interview indicated that Knowledge, Process failure and lack of patient centeredness were factors accounted for pre-analytical error. Alongside of the efforts to control laboratory error, this study highlighted complexity of pre-analytical error control efforts. Co-operation with clinicians and personnel outside the laboratory, process automation, computerized test requesting, procedure for specimen collection and training are of vital importance to make progress on pre-analytical testing process.
