As an international standard, compliance to ISO 17025 promotes confidence in laboratory operations, demonstrating they have the ability to produce valid results. “Consistent operation of the Laboratory” means that the laboratory maintains the requirements of ISO 17025 and produces valid results over time, i.e. consistently. To achieve this, processes inputs and outputs should be known and risks to disrupting the desired outcome must be identified through monitoring activities. All the risks that could impact quality objectives (such as turnaround time) and the quality of results must be controlled.
ISO 17025 assists by specifying the requirements to facilitate consistent operation. An example would be requirements for document and record control to ensure consistency of access and use between personnel. Another example would be the requirement Ensuring the validity of results, were the laboratory is required to monitor the consistency of method performance through internal and external quality control checks and act on significant variations.
