What ISO 15189:2022 Covers

Comprehensive requirements for quality and competence across the complete examination process.

Pre-Examination Phase

Test requesting procedures, patient identification and preparation, specimen collection, handling, transportation, and reception. Includes request review, patient preparation instructions, phlebotomy procedures, specimen integrity, and chain of custody requirements.

Examination Phase

Analytical methods, validation and verification procedures, metrological traceability, measurement uncertainty assessment where clinically relevant. Includes equipment management, reagent control, calibration procedures, and environmental conditions.

Post-Examination Phase

Result review and authorization, interpretation and reporting, critical value management, result release and communication. Includes turnaround time monitoring, report format requirements, and communication with healthcare providers.

Risk Management & Ethics

Risk-based approach to quality management, patient confidentiality, informed consent considerations, ethical review processes, and conflict of interest management throughout laboratory operations.

Personnel Competence & Training

Competence assessment and authorization procedures, continuing education requirements, supervision structures, and performance monitoring. Includes qualification requirements for different roles and competence maintenance programs.

Quality Control & EQA

Internal quality control programs, external quality assessment participation, proficiency testing enrollment, and alternative assessment where PT is unavailable. Includes performance monitoring and corrective action procedures.

Frequently Asked Questions

Is ISO 15189 mandatory for medical laboratories?
Depends on country and jurisdiction. Often voluntary but increasingly required by purchasers, health ministries, and accreditation programs. In the USA, it complements CLIA requirements but doesn’t replace CLIA obligations.
How is ISO 15189 different from ISO/IEC 17025?
ISO 15189 is specifically designed for medical laboratories with patient focus, clinical interfaces, and healthcare ethics. ISO/IEC 17025 is for general testing and calibration laboratories. Medical labs should use 15189 for clinical testing.
Do we need measurement uncertainty calculations?
For quantitative examinations where clinically relevant and fit-for-purpose. You must demonstrate an approach to uncertainty estimation and provide reasonable estimates based on your technical capabilities and clinical requirements.
Is external quality assessment (EQA/PT) required?
Yes, participation in EQA/proficiency testing programs is required where available. For tests where PT is unavailable, alternative assessment methods must be documented with rationales and outcomes tracked.
What about point-of-care testing (POCT)?
POCT programs can be managed under ISO 15189. Where required by the accreditation body, ISO 22870 may be added as a supplementary standard for comprehensive POCT accreditation coverage.
What’s the business case and ROI for ISO 15189?
Benefits include fewer errors and repeat testing, faster turnaround time stabilization, stronger clinician trust in results, improved tender eligibility, streamlined regulatory inspections, and enhanced reputation in healthcare networks.
How long does accreditation last?
Typically a 4-year accreditation cycle with annual surveillance assessments. The specific cycle length varies by accreditation body, but 4 years is the most common duration with interim monitoring.
