What is ISO 15189?
ISO 15189 is a quality and competence management standard developed specifically for medical laboratories. It sets requirements for laboratories to operate competently, impartially, and consistently, while ensuring the reliability and traceability of examination results.
The standard addresses both management system elements and technical requirements, including personnel competence, equipment validation, method verification, sample handling, quality assurance, and ethical practices.
ISO 15189 is used by medical laboratories to demonstrate conformity with recognised international requirements for laboratory quality and competence. It does not prescribe clinical decision-making or guarantee patient outcomes.
