Abstract
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.

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
