To implement the relevant regulations on laboratory accreditation, a comprehensive evaluation and qualification accreditation of the laboratory management level and technical ability is conducted by a third party organization to prove to the relevant parties that the laboratory has a certain technical ability and qualification. At the same time, the management level and technical capabilities of the laboratory can be improved. In order to pass the laboratory accreditation, adequate preparations should be made in terms of organizational structure, personnel capacity, facilities and equipment, and effective operation of the quality management system.
