It replaces ISO 22870:2016 for POCT, embedding these requirements within the main standard. In Malaysia, laboratories accredited to earlier versions, such as ISO 15189:2012, are transitioning to the 2022 standard, with a typical three-year period provided by accreditation bodies like the Department of Standards Malaysia (DSM) to complete this shift.

ISO 15189 Certification Process in Malaysia

Achieving ISO 15189 certification in Malaysia involves a structured process, guided by accreditation bodies such as the Department of Standards Malaysia (DSM) under the Skim Akreditasi Makmal Malaysia (SAMM). Here’s a step-by-step breakdown:

1. Preparation and Commitment

The journey begins with a commitment from laboratory management to pursue certification. This involves understanding the standard’s requirements, allocating resources, and appointing a quality manager to oversee the process. Laboratories may also engage consultants familiar with ISO 15189 to provide guidance.

2. Gap Analysis

A gap analysis is conducted to compare the laboratory’s existing practices against ISO 15189 standards. This identifies deficiencies in areas such as personnel training, equipment calibration, documentation, and quality control. The findings form the basis for an action plan to address shortcomings.

3. Implementation

Laboratories implement necessary changes, including:

• Quality Management System: Establishing policies, procedures, and work instructions to ensure consistency and compliance.

• Personnel Competence: Training staff to meet technical and quality requirements, ensuring they are qualified and skilled.

• Equipment and Supplies: Calibrating and maintaining equipment, validating reagents, and ensuring reliable supplies.

• Pre-Examination Processes: Standardizing sample collection, handling, and transport to prevent errors.

• Examination Processes: Validating test methods and ensuring accuracy and precision in results.

• Post-Examination Processes: Ensuring proper reporting, interpretation, and delivery of results to clinicians.

4. Internal Audit and Management Review

Once changes are implemented, an internal audit evaluates compliance with ISO 15189. This is followed by a management review meeting to assess the QMS, address non-conformities, and plan corrective actions. Regular reviews ensure continuous improvement.

5. Application to Accreditation Body

Laboratories submit an application to an accreditation body like DSM, along with supporting documentation such as quality manuals, procedures, and records. DSM operates under the SAMM scheme, aligning with international standards set by the International Laboratory Accreditation Cooperation (ILAC).

6. External Audit

The accreditation body conducts a two-stage audit:

• Stage 1: Documentation Review: Assessors verify that the laboratory’s documentation meets ISO 15189 requirements.

• Stage 2: On-Site Assessment: Auditors evaluate the laboratory’s operations, including personnel competence, equipment, and processes. They sample sites, services, and functions to ensure compliance.

If non-conformities are identified, the laboratory must address them within a specified timeframe, implementing corrective actions to close gaps.

7. Certification and Surveillance

Upon successful closure of non-conformities, the laboratory receives ISO 15189 accreditation, valid for a defined period (typically three years). Regular surveillance audits by the accreditation body ensure ongoing compliance and improvement. Laboratories can check their certification status on platforms like DSM’s SAMM search page.
