What is proficiency testing?

For ensured quality, proficiency testing is a proven tool for monitoring, securing and improving the analytical, physical, microbiological and sampling qualities of an organization.

Regular participation in proficiency testing is required for laboratories that want to comply with international standards (ISO) and (inter) national legislation. In addition to the competence of a laboratory, proficiency tests are also a basis for the integrity and trust of the customer, accreditation body, and management.

What are the benefits of routine proficiency testing?

After receiving a proficiency test report, the scores can be assessed on performance. In the event of poor performance, corrective measures will be required to be able to properly guarantee the quality.

Internally, the obtained proficiency test material and / or the results of the proficiency test can also be used for other daily quality assurance purposes, such as specific validations or harmonization of new analysis methods or sampling techniques. An example of this is the determination of the precision and correctness in varying matrices and parameters.
