Introduction
Proficiency Testing (PT) scheme participation allows laboratories to:
- objectively monitor and improve the quality of their measurement results in terms of accuracy and comparability,
- independently demonstrate the continued competency of their analytical staff, and
- demonstrate the effective maintenance of quality assurance systems.
NMISA is committed to supporting laboratories through the provision of PT schemes that afford participating laboratories the opportunity to regularly demonstrate their analytical measurement competence.
