What is laboratory proficiency testing?

Use laboratory proficiency testing (PTs) to comply with your labs accreditation requirements and evaluate your analysts’ performance. You can conduct one for specific tests or measurements or use it to monitor your labs continuing performance. PTs are an integral part of a quality management system (QMS) under quality assurance and control (QA/AC). Understanding the core components of the QMS, how the laboratory operates is an important part of passing any PT test.
