Introduction. This study shows that analyzing the status of building and equipmant, stuff contribution, trainings had been affect the process of Public Health Laboratories growing.  Aim of the study. It was aimed that providing the needs and demands of the Public Health Laboratories on a timely and accurate basis and making general state detections to develope standardization.Material and methods. In the work done, general information inventory, collected by Public Health Laboratory Planning and Coordination Unit's general information document (F35), was emailed to 83 Public Health Laboratory (5). This inventory was structured in excel format and consist of some parts suchs as general informations, status of buildings, staffs and finally equipments. The inventory provided by laboratories was sent to Head Department of Public Health Laboratories (PHL)  via email to evaluating them. Results. Altough the 49% of the buildings belongs to PHL, buildings are very old. That's why this buildings have been taken to investment program. Since departments prefer the significant job groups and circulating capital methods; it is obviously seen that relocation or departuring the trained stuff was directly affect the motivation and the peace between the workers negatively. Laboratories have been equiped by the department and therefore the substructue was completed. According to the statistical research, there were a increasing rate of buying total equipment with 75% between the years of 2012-2013, with 40% between 2013-2014 and 9% between 2014-2015. Moreover, the most increasing number of training personnel in between 2014 and 2015 as 46% was observed. As a result of a complete substructure, it is stated that stuff needed more and more education. Conclusion. In the light of our findings, according to the TS EN ISO/17025, substructure was generated to make standardization and labs have been accredited. Furthermore,there have always been studying to decrease deficiencies like equipment, substructure, personnel and education. Hence, this study has been playing a huge role on PHL that to give national and international standart service.    Keywords: Laboratory, building, equipment, personnel, standardization, improvement, accreditation
