A clinical laboratory needs more than accurate testing equipment to provide dependable laboratory services. Consistent procedures, competent personnel, controlled processes, reliable records, and effective quality management are equally important. ISO 15189 accreditation provides a recognized framework for medical laboratories to demonstrate quality and competence. This article explains why ISO 15189 matters, what it covers, and what laboratory owners should consider before starting accreditation.
What Is ISO 15189?
ISO 15189 is an international standard that specifies requirements for quality and competence in medical laboratories. The standard is designed specifically for medical laboratory activities and considers the complete laboratory workflow, including pre-examination, examination, and post-examination processes.
For a clinical laboratory, this means quality is not limited to the testing stage. Activities such as patient preparation, sample collection, sample identification, transportation, examination procedures, result reporting, and communication can all influence the usefulness of laboratory results.
ISO 15189:2022 provides a structured approach for laboratories to establish, implement, maintain, and continually improve their management and technical processes.
Why ISO 15189 Accreditation Matters
1. Creates a Structured Quality Management System
One of the important benefits of ISO 15189 accreditation is the development of a systematic quality management framework.
A laboratory may perform hundreds or thousands of examinations through different processes and personnel. Without clearly defined procedures and responsibilities, variations can occur.
ISO 15189 helps laboratories establish controlled processes for areas such as:
Document and record management
Personnel responsibilities and competence
Equipment management
Examination procedures
Quality control
Risk management
Internal audits
Complaints and feedback
Corrective and improvement actions
This structured approach can make quality management a routine part of laboratory operations rather than an activity performed only before an assessment.
2. Demonstrates Laboratory Competence
Clinical laboratory accreditation is concerned with both quality and technical competence. A laboratory needs appropriate personnel, suitable equipment, controlled examination methods, and processes that support reliable results.
For example, when a laboratory introduces a new examination method, it needs to consider whether the method is appropriate for its intended use, whether personnel have the necessary competence, and whether equipment and supporting processes are adequately controlled.
By addressing these areas systematically, ISO 15189 helps a medical laboratory establish evidence of competence within its defined scope.
3. Covers the Complete Testing Process
A laboratory result can be affected by activities before and after the actual examination.
Consider a blood sample that is incorrectly identified or transported under unsuitable conditions. Even if the analytical instrument performs correctly, the resulting report may not provide the intended clinical information.
This is why ISO 15189 addresses different stages of laboratory operations. The framework includes considerations related to:
Patient and user requirements
Examination requests
Sample collection and identification
Sample transportation and handling
Examination procedures
Quality control
Result validation and reporting
Communication with users
Complaints and feedback
Risk management
This process-based approach helps laboratories examine quality across the entire service cycle.
ISO 15189 and Clinical Laboratory Accreditation in India
Laboratories considering clinical laboratory accreditation in India should first understand the requirements applicable to their activities and proposed scope.
The laboratory accreditation process requires preparation rather than simply submitting an application. A laboratory generally needs to establish its management system. demonstrate technical competence, maintain appropriate records, and be prepared for assessment against applicable requirements.
A practical preparation sequence can include:
Define the laboratory's accreditation scope.
Review the applicable ISO 15189 requirements.
Conduct a gap assessment.
Develop and implement required processes.
Establish documentation and records.
Verify personnel competence.
Review equipment and examination methods.
Conduct internal audits and management review.
Submit the accreditation application.
Address findings identified during assessment, where applicable.
The exact requirements and assessment procedure depend on the selected accreditation body and the laboratory's scope.
Choosing Accreditation Bodies for Medical Laboratories
Selecting among accreditation bodies for medical laboratories is an important step for a laboratory owner. The laboratory should review the accreditation body's applicable scope, requirements, assessment process, documentation, and recognition arrangements before proceeding.
FDASIndia states that its accreditation management system follows ISO/IEC 17011:2017 and that it provides accreditation for medical laboratories against applicable requirements, including ISO 15189:2022.
Laboratories should always refer to the current requirements and application documents of the selected accreditation body because accreditation requirements and procedures may be updated.
ISO 15189 vs Other Laboratory Accreditation Standards
Different laboratory activities may require different accreditation standards. ISO 15189 is specifically focused on medical laboratories, while ISO/IEC 17025 addresses the competence of testing and calibration laboratories.
Therefore, terms such as testing lab accreditation, medical device testing lab accreditation, and calibration lab accreditation should not automatically be treated as equivalent to medical laboratory accreditation.
The appropriate standard depends on the laboratory's activities and intended accreditation scope.
For a clinical laboratory providing medical examination services, ISO 15189 provides a framework specifically designed around medical laboratory quality and competence.
What Should a Medical Laboratory Prepare?
Before applying for medical lab accreditation, a laboratory should assess whether its existing processes are capable of meeting applicable requirements.
Important preparation areas include:
Clearly defined accreditation scope
Qualified and competent personnel
Controlled examination procedures
Equipment maintenance and monitoring
Appropriate quality control processes
Method verification or validation, where applicable
Sample collection and handling procedures
Result reporting controls
Risk identification and management
Internal audit arrangements
Management review
Complaint handling
Corrective action and continual improvement
Maintaining objective evidence is also important. Procedures should be supported by appropriate records demonstrating that the laboratory actually follows its defined processes.
How ISO 15189 Can Support Laboratory Improvement
Accreditation should not be viewed only as a certificate for display. Its broader value comes from implementing a management system that supports consistent laboratory operations.
For example, if a laboratory identifies repeated errors in sample identification, it can investigate the cause, implement corrective action, monitor whether the action is effective, and review the process for further improvement.
Similarly, regular monitoring of equipment, personnel competence, quality indicators, and examination processes can help laboratory management identify areas requiring attention.
This makes quality management an ongoing activity rather than a one-time preparation exercise.
