Abstract: ABSTRACT Introduction: In the new Millennium, the quality of TB laboratory diagnosis in both public and private health facilities was often a direct reflection of the success of TB control programmes and a key component of the DOT strategy, yet it was one of the most neglected components of these programmes. Objective: To assess the quality of TB Laboratory Diagnosis in selected public & private Health Facilities in Oromia Region. Methodology: Crossectional survey design was conducted out in 60 randomly selected public & private TB laboratories between 3rd January –12 th May 2011, in purposively selected 3 zones of Oromia Region. Sixty TB laboratory department heads were interviewed, 270 patients records were reviewed, 384 TB laboratory clients were interviewed and panel testing for 20 laboratory technicians were done.Odd ratios and logistic regression were employed to see if any association exits among the three quality parameters. Data were entered and analyzed using SPSS version 15.0 software and findings at 95% Confidence interval and p value of 0.05 were used for statistical significance. Result: The study shows that staff training is a neglected issue in most private TB laboratories which are separated structurally from NTP, high false negative discordant rate of AFB result, weak supervision mechanism, and lack of checking the quality of sputum sample. Higher proportions of patients visited the TB laboratories were dissatisfied with lack of respect from the providers. Statistically significant association was observed between structure and process quality (OR =2.9(1.46-5.7; P=0.01) and between process and output quality parameters (OR=3.2(3.13-10; P=0.02). Conclusion and Recommendations :The quality of TB laboratory diagnosis in both public and private TB laboratories in Oromia region were poor in that laboratory technicians training was not satisfactory, high false negative discordant rate of AFB result and the pattern of supervision was weak and unplanned. So mechanisms of improving the different stages of TB laboratory diagnosis especially staff training, displaying and follow smear preparation and sticking to the National TB laboratory manual were strongly recommended.
