Currently we aimed to assess laboratory performance of current situation by implementation of quality assurance program. A total of 136 laboratories were randomly selected and classified based on instruments, personnel, reagents and distribution of population (class A, B and C). Two pathological lyophilized control sera were sent to each laboratory for estimation of Glucose and Creatinine levels blindly as routine test. Data regarding reagents, type of instruments and personnel were measured. Independent t-test analysis showed significant decrease of class C mean glucose level as end point mode p-value 0.017, while insignificant difference was observed in class B p-value 0.211 in comparison with highly quality and well equipped reference (Class A). Fixed timed mode which presented by mean creatinine level showed significant decreases of both classes B and C with p-value 0.038 and 0.014 respectively, versus class A laboratories. Z-score results found significant differences of unsatisfied results of blood glucose level obtained from class B and C when compared with Class A p-value 0.002, also creatinine revealed similar results with p-value 0.001 of both classes. The study concludes that, type of instruments, validity of reagents, lack of training and poor quality system have an adverse effect on accuracy and reliability of both mode of reactions.
