international organization for standardization ( iso ) had published an international standard for medical laboratories , iso:15189  medical laboratories  particular requirements for quality and competence  ( 1 ) . it was not feasible to implement the requirements of iso:15189 all at once in medical laboratories in different sectors and in different provinces , so it had been decided to define the minimal quality requirements that could be mandatory for all clinical laboratories throughout the country . to do so reference health laboratory ( rhl ) of ministry of health organized expert committees , and finally in september 2007 national standard manual was finalized and officially announced as the minimal quality requirements for all medical laboratories in the country ( 2 , 3 ) . with the finalization the aim of the workshops was training capable and knowledgeable pool of auditors in accordance with national standards and its respective checklists . apart from auditing laboratories , rhl has performed benchmarking auditing of medical laboratory network ( surveys ) in provinces . seasonally , laboratory auditors gather in one selected province to audit a noticeable fraction of its total laboratories based on the national standard checklist ( 3 ) . 12 benchmarks performed in tehran and alborze provinces in 2010 ( on that time these two provinces were merged as one province named tehran province ) . regarding too many active laboratories in these two provinces , this benchmark performed in three stages : 
 public hospitals : 84 public hospitals were audited by 60 auditorsprivate hospitals : 54 private hospitals were audited by 70 auditorsoutpatient , private medical laboratories public hospitals : 84 public hospitals were audited by 60 auditors private hospitals : 54 private hospitals were audited by 70 auditors outpatient , private medical laboratories the results of these audits are the main interest of this study . through the discussion and analyzing process we try to compare different processes , their quality and accordance with national standard measures between public and private hospital laboratories . the assessment of the medical laboratories in tehran and alborz provinces were performed by the trained auditors and based on the national standard and its respective checklist . the questions were categorized based on the requirements in national standard . there were four options for each question :  yes  ,  no  ,  corrective action is required  and  not applicable  . yes  suggested that the requirement is completely fulfilled ;  no  showed that the requirement has not been fulfilled yet , corrective action is required  showed that an attempt to accomplish the requirements was tried but it is not totally completed and further action is required , and  not applicable  showed that the requirement is irrelevant in this precise laboratory . the results obtained from each respective checklist with the laboratory s informational data were entered in software for further statistical analysis . the reason for this study was to compare the assessment results of 84 public hospital laboratories with 54 private hospital laboratories . the comparison was done on the personnel management , biosafety , equipment management , environment , pre - analytical , analytical and post - analytical processes , quality assurance processes , purchasing and inventory , referral and referee laboratories relations , non - conformity management . we tried to define the weakness and threats in both settings and compare their success ratio . the results of the questionnaire with respecting ethical issues are presented in tables 1 to 3 . several studies comparing the health service of public and private sector , as some of them are as follows : a systematic review of comparative quality of private and public ambulatory health care in low and middle income countries show both public and private sectors , scored low on infrastructure , clinical competence and practice , nevertheless private sector performed better with regard to responsiveness and effort . synthesis of qualitative components indicates the private sector is more client centered ( 4 ) . other study in south korea revealed public hospital workers were stereotyped as lazy and incompetent , and public hospitals were portrayed as poorly managed and of low quality , unlike the claims made by the government ( 5 ) . in a study in bangladesh about public and private hospitals , private hospitals were evaluated better on responsiveness , communication , and discipline ( 6 ) . in combination with other evidence on health service delivery in china , it was suggested that changes in ownership type alone are unlikely to dramatically improve or harm overall quality ( 7 ) . comparison of different processes in two sectors : 
 - personnel managementprivate sector shows a 10% better implementation ratio in comparison to the public sector . during discussion with the public laboratory directors it was noticed that they encounter certain managerial restrictions , which has affected their field of action as the laboratory director . in some of the laboratories in the public sector , the directors were supposed to only supervise the technical issues and the personnel management was not one of their responsibilities . this issue had apparently affected many aspects of the personnel management such as trainings or related corrective actions . due to our observation the training was one of the most affected areas.on the other hand as some of the legal regulations such as the permit requirements do not include the public sector , the directors did not feel the necessary responsibility toward the standard implementation.who in one of its reports brought highly trained individuals tend to move to more stable ( and available ) jobs in the private sector ( 8).- biosafetyno regulation or guideline can ensure safe practices . individual and organizational attitudes regarding safety will influence all aspects of safe practice , including willingness to report concerns , response to incidents , and communication of risk ( 9).private laboratories showed 12% better implementation rate . the detailed analysis of the questions showed that the public laboratories problem area rests in waste management and providing the personnel protective equipment . we concluded that this part is more due to the budget.- equipment managementpublic laboratories showed less achievement in this field . the personnel are neither well convinced to the importance of documentation nor have received the required sufficient training . the failure is most apparent at usage of control material and also at generating the records of all procedures.- environmentone series of five papers shows the private sector performs significantly better than public sector institutions . this series examines this variation in performance with the objective of identifying successful approaches to the management of medical equipment ( 10).public laboratories showed 10% less achievement in environment requirements . this was mainly due to the old structure of a few hospitals that has affected the total percentage dramatically.class ii biological safety cabinet only existed in 40% of laboratories irrespective of the group that they belong to . class ii biological safety cabinet is mandatory for the laboratories that are supposed to perform blood culture . reference health laboratory should pursue this issue for dedication of necessary budget.- pre - analytical , analytical and post analytical procedurespublic laboratories showed less achievement in these fields . fortunately the weakness was not at the technical aspect of the laboratories but as mentioned earlier it was on documentation management.- quality assuranceat this category , which we believe is one of the most fundamental and essential parts for assuring the quality of the results , unfortunately both groups showed weaknesses in these areas and achieved almost 35% . the personnel were not able to analyze the result of quality control procedures and implement the corrective action.we also find out that to empower our assessing tool , we should increase the number of our questions in this field.- purchasing and inventorydue to the centralized purchasing department in hospital , laboratory director had minimal say in choosing the supplier . this problem was more highlighted in public hospitals.- referral and referee laboratorieswe noticed that only a handful of public laboratories were a referral laboratory with full capacity . in other cases though the laboratory was not capable of performing all the desired tests but they do not participate in sending the samples . it should be noted that this issue is not in accordance with national standards , and may cause serious problems especially in terms of biosecurity . it also may affect the quality of specimen because of improper condition of specimen transport . it is strongly recommended that there should be determined policy and documented procedures concerning the test performing and their turnaround times in hospital laboratories . requests of clinicians of different wards of the hospital should take in to the account . the president of hospital should approve the list of performing tests and provide the needed resources.if for any reason the laboratory could not perform a certain groups of tests , the specimen could be sent to a referral laboratory according the related documented standards.- non - conformity managementnone of the groups were able to show any credibility in management of non - conformities and also corrective and preventive actions . since management of the nonconformities is considered as a more mature step in establishing quality management system , the results of evaluation indicated that all laboratories in public and private sectors had difficulties in detecting the nonconformities and take proper corrective and preventive actions . training in this field and performing internal audit as well as documentation of the detected nonconformities and taking corrective actions should be strongly considered . -

purchasing and inventory due to the centralized purchasing department in hospital , laboratory director had minimal say in choosing the supplier . - referral and referee laboratories we noticed that only a handful of public laboratories were a referral laboratory with full capacity . in other cases though the laboratory was not capable of performing all the desired tests but they do not participate in sending the samples . it should be noted that this issue is not in accordance with national standards , and may cause serious problems especially in terms of biosecurity . it also may affect the quality of specimen because of improper condition of specimen transport . it is strongly recommended that there should be determined policy and documented procedures concerning the test performing and their turnaround times in hospital laboratories . requests of clinicians of different wards of the hospital should take in to the account . the president of hospital should approve the list of performing tests and provide the needed resources . if for any reason the laboratory could not perform a certain groups of tests , the specimen could be sent to a referral laboratory according the related documented standards . -

in september 2007 national standard manual was finalized and officially announced as the minimal quality requirements for all medical laboratories in the country . 
 apart from auditing laboratories , reference health laboratory has performed benchmarking auditing of medical laboratory network ( surveys ) in provinces . 
 12th benchmarks performed in tehran and alborz provinces , iran in 2010 in three stages . 
 we tried to compare different processes , their quality and accordance with national standard measures between public and private hospital laboratories . 
 the assessment tool was a standardized checklist consists of 164 questions . 
 analyzing process show although in most cases implementing the standard requirements are more prominent in private laboratories , there is still a long way to complete fulfillment of requirements , and it takes a lot of effort . 
 differences between laboratories in public and private sectors especially in laboratory personnel and management process are significant . 
 probably lack of motivation , plays a key role in obtaining less desirable results in laboratories in public sectors .
