Introduction
Proficiency testing (PT) is no longer optional for laboratories aiming to maintain accuracy, credibility, and international recognition. Whether you operate a clinical, food, environmental, or industrial laboratory, participation in accredited proficiency testing programs is essential for compliance with ISO/IEC 17025 and ISO/IEC 17043 requirements.
In this article, we explain what proficiency testing is, why it matters, and how it directly impacts your lab’s performance and accreditation success.
What Is Proficiency Testing?
Proficiency testing is an external quality assessment where multiple laboratories analyze the same samples and compare results against assigned values or peer performance.
According to ISO/IEC 17043, proficiency testing helps laboratories:
- Validate technical competence
- Detect analytical errors
- Improve measurement accuracy
- Demonstrate compliance to accreditation bodies
Why Proficiency Testing Is Critical for Accreditation
Accreditation bodies such as ILAC and national accreditation authorities require laboratories to participate in regular, relevant PT schemes.
Failure to participate or poor PT performance can lead to:
- Major non-conformities
- Suspended accreditation
- Loss of client trust
