Proficiency tests are one of the requirements to obtain and maintain ISO 17025 accreditation. A distinction that is the benchmark standard for testing and calibration laboratories seeking to demonstrate their competence and reliability.
At GSC, we understand the importance of these exercises and offer specialized solutions to help laboratories meet this requirement. Therefore, if you want to learn about the key role of proficiency tests and their benefits, keep reading.
Types of Proficiency Tests
Proficiency tests are evaluations in which several laboratories analyze similar samples under controlled conditions and compare their results. Their objective is to measure the performance and technical competence of the participating laboratories. The main types of proficiency tests include:
- Organized intercomparison exercises: An organization distributes identical samples to several laboratories and analyzes the results.
- Collaborative test: Evaluates an analytical method, with participation from laboratories that are experts in the method being assessed.
- Certification test: A property value is assigned to a material (sample) and intercompared among different laboratories (method variability).
- Proficiency testing schemes: A consensus value is established based on the mean/median of participants, and each result is later compared to this using a statistic such as the z-score.
Benefits of Proficiency Tests
The proficiency tests from GSC are a fundamental tool for accreditation and continuous improvement of testing and calibration laboratories. At GSC, we provide expert guidance and access to intercomparison programs that ensure compliance with ISO 17025 and strengthen laboratory credibility.
Demonstration of Technical Competence
Participating in proficiency tests allows laboratories to demonstrate their ability to produce reliable and accurate results—an essential requirement for ISO 17025 accreditation.
Identification of Areas for Improvement
Comparing results with other laboratories helps detect deviations or inconsistencies, enabling improvements in techniques, procedures, and calibrations.
Compliance with Regulatory Requirements
The ISO 17025 standard requires laboratories to evaluate their performance through proficiency testing. Meeting this requirement facilitates obtaining and maintaining accreditation. To achieve this, participation with accredited providers such as GSC is essential.
Increased Client Confidence
Clients look for accredited laboratories that provide precise and consistent results. Participation in proficiency tests strengthens the laboratory’s reputation and builds trust in its services.
