Back ground:-Participating in proficiency testing ( PT) is crucial for clinical laboratories to evaluate their gaps based on the feedback from PT providers, and taking corrective action should used to improve the quality of service provisions. Objective:- The objectives of this study was to evaluate the utilization and challenges of RBC, 56.6% for SGOT, 44.4% for SGPT,75% for Syphilis, 75.4% for Total bilirubine, 79.2% for Urea, 39.9% for WBC was identified in this study. Conclusion:- PT is not utilized effectively among 12 governmental hospital laboratories in Addis Ababa through 6 cycles. There are challenges for effective utilization of PT (the major identified challenges was knowledge gap, poor staff commitment ,equipment down and reagent out of stock) so stakeholders and collaborators need to resolve or minimize the challenges for effective utilization of the coming PT. Key words:- Panel Test, EQA, Utilization, Participation rate, Trend of analytical score proficiency test panel in government hospitals at Addis Ababa. Method:- Retrospective study was conducted among 12 government hospitals laboratories in Addis Ababa, who had been participated in proficiency tasting schemes for 20 clinical laboratory test parameters in 6 cycles from 2012 to 2013 G.C. Data on institutional performance and test results plus problems of each parameter participation were extracted from proficiency test feedback reports stored at the data base of Ethiopian Public Health Institute(EPHI). Focused group discussion (FGD) and in-depth interview were used to assess the major challenges of institution participating PT. Trend of analytical performance scores of institutions in six cycles was analyzed using SPSS version 20. Likewise, qualitative data obtained through the focus group discussion and in-depth interview were classified in major thematic areas and summarized accordingly. Result:- A total of 12 hospital participated, of these 5(41.7%) owned by federal ministry of health and 4(33.3%) were under Addis Ababa Regional health Bureau plus 3(25.0%) were uniformed service hospitals. A total of 12 laboratories participated in all six cycles of 20 test parameters panel tests. The overall acceptable analytical performance score was 2643 of 6984 PT challenges (37.85%) and the overall participation rate throughout the 6 cycle was645 of 1440 (44.7%). Of reviewed performance of 20 analyte in six cycle, the total failure rate participant institution was 4341 of 6984 PT challenges(62.15%) Of which , 2880 of 6984(41.23%)of the observed EQA failures occurred in 4 of the 12 laboratories. EQA fail rates among the 12 laboratories were 63.8% for AFB,50% for ALP,48.6% for CD4, 68.1% for creatinine,75% for Direct bilirubine,88.9% for gram stain,68.1% for HBsAg,76.3% for HCV,44.5% for Hgb, 51.4% for HIV, 55.6% for morphology identification,82.7% for parsitology,38.9% for PLT, 50.0% for
