With the start of the new corona virus pandemy in 2019 from the city of "Wuhan" in China and confirmation and warning of the Iranian Ministry of Health and Medical Education in February 2020 and considering the importance of timely laboratory diagnosis of the new corona virus, a number of Public and private laboratories gradually took responsibility for the molecular diagnosis of this virus. A review of the events of this era can reveal the strengths and weaknesses of the decisions and actions taken and the challenges of this path in the implementation phase from a supervisory point of view.

This study is a review based on the records and information available in the management of laboratories affairs of vice president of treatment of IUMS in connection with the supervision of the laboratories operating within the regulatory area of the said university within the period of March 2020 to the end of July 2022.  The obtained results have been examined in the areas of: testing license, laboratory supervision, data collection, handling of complaints and ethical challenges.

With the start and continuation of the Covid pandemy and the prediction of increase in the number of cases of the disease and the need to speeding up in the definite diagnosis of suspected Corona virus patients by using paraclinical services including laboratory, the Ministry of Health took actions to use the capacities of the private sector in addition to the public sector. In this way, the laboratories applying for participation in the molecular diagnosis program of the new corona virus entered the field after completing the process of obtaining a license, the framework of which was announced by the health ministry. Due to the fact that a significant number of laboratories with a Covid license are established within the regulatory area of Iran University of Medical Sciences (91 laboratories out of a total of 404 Covid laboratories in the country), the examination of the performance of these laboratories can be a reflection of the general situation of laboratories across the country, including the amount of services provided and the most important supervisory problems, including Quality control and interpretation of results, recording of unconformities and collection, storage and transfer of samples, etc.
Also, along with these issues, the importance and necessity of recording and collecting the laboratory diagnosis data of the Covid-19 disease and the problems related to it in this epidemic have been considered and investigated. Among the other important challenges of this era are complaints, the most of which is the involvement of unrelated people in the matter of taking samples for the Covid test and the inconsistency of the results obtained in different laboratories, etc.
Considering that the Covid pandemy still continues and improving the situation and solving the existing challenges can have a significant impact on the health of the people, it seems necessary to use the results of this study to solve the problems.

Saving is not underspending, but managing costs for what is available.
To save and operate efficiently in any center, we must focus on the most key core and its part, namely management.
Process management is the effective and efficient use of material and human resources in planning, organizing, mobilizing resources and facilities, guidance and control, which is done to achieve organizational goals and based on an accepted value system.
It has been a long time since the laboratory centers facing financial crisis and bankruptcy threatening.
Among the important reasons, we can mention the impact of mismanagement of equipment, warehouse and purchase of consumables.
One of the other issues related to the scope of management and the direct impact on the labchr(chr('39')39chr('39'))s income, the managerchr(chr('39')39chr('39'))s dealing with the staff and its impact on the clients.
If you have a good attitude towards your employees as a boss or manager, you will see a positive impact on the clientchr(chr('39')39chr('39'))s absorption and the laboratory revenue and the economic profit of your center, while the opposite is also true.
The choice of labor has a definite and direct effect on the cost and income of the laboratory, as it can.
Make your lab a brand in the region and beyond, and it could also bankrupt it.
So be very careful in choosing your staff, which is one of the basic and important management principles.
Note that to select a good employee for a laboratory, you need to consider indicators such as customer behavior skills, time management skills, teamwork skills, communication skills and professional ethics skills.
apart from these matters , we chr(chr('39')39chr('39'))d better deal with taxes that can be said in all the lab centers involved.
By law, business owners are required to pay taxes to the Treasury Department based on the type and volume of activity, which has become a concern for laboratory owners.

The measurement results do not mean a single concept and they should be standardized and compared. After measuring and comparing with standards necessary measures to control and prevent environmental hazards in the work and impact of these factors on the results will be made. Therefore, the identification of environmental factors in the laboratory is of particular importance. Generally environmental factors in the laboratory are as follows: Physical factors: noise, vibration, lighting, heat, humidity, cold, pressure, radiation. Chemical elements: Chemical materials: solid, liquid, gas and steam, suspended particulate matter (dust, smoke, fog, etc.) Biological factors (biological): viruses, bacteria, parasites, fungi and so on. Ergonomic factors (poor ergonomic conditions): improper body posture while working, physical mismatch between the worker and the work assigned, appropriate tools and so on. Mechanical factors: Any factor in the workplace which caused the accident or injury such as a work tool, sharp edges or works at height. If optimal, recommended conditions and standards for the elimination of harmful factors are not respected in workplace will lead to damaging factors and will certainly affect the accuracy of the results, so the identification and elimination of harmful factors are of importance.

ILAC is the international organization for accreditation bodies operating in accordance with ISO/IEC 17011 and involved in the accreditation of conformity assessment bodies including calibration laboratories (using ISO/IEC 17025), testing laboratories (using ISO/IEC 17025), medical testing laboratories (using ISO 15189) and inspection bodies (using ISO/IEC 17020). Accreditation is the independent evaluation of conformity assessment bodies against recognized standards to carry out specific activities to ensure their impartiality and competence. In this paper, we introduce the ILAC and its procedures.

Although a few laboratories have been implemented the Quality Management System (QMS), the importance of laboratories’ results encourages them to be interested in establishing QMS according to ISO9001. This article describes the reasons and benefits of implementation the standard ISO9001 in laboratories.
