It was conducted by sending questionnaire to responsible persons in customer organizations, and the study samples were 324 respondents. The analysis of the completed questionnaires revealed that the main service from the BLQS was clinical microscopy (86.12% of the BLQS customers), clinical immunology service at the public sector (39.09%), and clinical chemistry service at the private sector (45.89%). Comparison of satisfaction level using Likert’s scale and t-test of satisfaction level showed a significantly high level of satisfaction for the service quality of all three groups of service providers (p<0.05). Additionally, a test of average satisfaction with the services in the custom ers of different age ranges was performed using One-way ANOVA and least square difference (LSD) method, and it was found that the group of 51-60 years old was significantly satisfied with the service quality of the analysis at the BLQS when compared to the groups of 21-30, 30-40 and 41-50 years old (p<0.05).
