Proficiency Testing and Interlaboratory Comparison Programs

Proficiency Testing (PT) and Interlaboratory Comparison (ILC) programs are essential for demonstrating laboratory competence and ensuring the accuracy, reliability, and consistency of test results. They enable laboratories to compare their performance with peer laboratories, identify opportunities for improvement, support compliance with ISO/IEC 17025 accreditation requirements, and strengthen confidence among customers, regulatory authorities, and accreditation bodies through objective and independent performance evaluation.
