Every measurement and analysis performed in laboratories represents far more than simply producing a result. The accuracy, reliability, repeatability, and comparability of the results obtained form the foundation of scientific studies, production processes, environmental monitoring, food and healthcare applications, and critical decision-making across numerous industries.
PT Nexus – Connecting Laboratories. Advancing Quality. provides Proficiency Testing (PT) and Interlaboratory Comparison (ILC) programs designed to support laboratories in objectively evaluating their technical performance, monitoring the reliability of their measurement results, and continuously improving their quali

Compliance with international standards (ISO/IEC 17025, ISO 15189, etc.) and meeting accreditation requirements necessitate laboratories to regularly participate in proficiency testing (Proficiency Testing – PT). However, each laboratory’s analysis portfolio, testing methods, and sample matrices differ from one another.
Standard proficiency testing programs may not always meet the specific needs of all laboratories. This is precisely where Custom Proficiency Testing, the Custom PT Assurance Model, and the Custom Proficiency Testing Request System come into play.
