**Proficiency Testing**

Proficiency testing is a quality assurance process used to evaluate the performance and accuracy of laboratories, testing facilities, or analysts. By comparing results from the same samples across multiple participants, proficiency testing helps identify strengths and areas for improvement, ensuring reliable and consistent testing outcomes. This practice is essential in fields such as clinical diagnostics, environmental analysis, and manufacturing, where accurate data is critical for decision-making and compliance with industry standards.
