ISO 15189 Medical Laboratory Accreditation
ISO 15189 Medical Laboratory Accreditation
-
Accreditation: A tool to demonstrate the competence of medical laboratories and ensure the delivery of timely, accurate and reliable results.
-
Medical laboratory services are essential in the diagnosis and assessment of the health of patients. Their services encompass arrangements for requisition, patient preparation, patient identification, collection of samples, transportation, storage, processing and examination of clinical samples, together with subsequent result validation, interpretation, reporting and advice. Medical laboratory services should therefore meet the needs of all patients, clinical personnel responsible for patient care and any other interested parties.
The laboratory’s aim is not only to provide accurate results, but to do so on the right patient within a meaningful timeframe as regards clinical management, using appropriate laboratory procedures and with a respect for ethics, confidentiality and the safety of the patient. -
A recognition of competence
-
To demonstrate the quality and reliability of their services, medical laboratories can seek accreditation to ISO 15189:
Medical laboratories – Particular requirements for quality and competence, an internationally recognised standard that contains the requirements necessary for diagnostic laboratories to demonstrate their competence to deliver reliable services.
ISO 15189 covers the essential elements for medical laboratories to demonstrate the quality and competence of their services, as well as to consistently deliver technically valid test or “examination” results as they are known in the standard.
The standard, which has been developed with strong involvement from the medical, scientific and clinical community, is forthe use of medical laboratories in developing their management systems and maintainingtheir own competence; and for accreditation bodies to confirm or recognise the competence of these laboratories through accreditation. -
Medical laboratory Accreditation
-
Accreditation to ISO 15189 involves the independent assessment of a laboratory to determine competence, impartiality and consistency. It addresses the qualifications and on-going competency of personnel involved in medical laboratory examinations, the laboratory accommodation, equipment, reagents and supplies, pre-analytical and analytical factors, quality assurance considerations, and post-analytical factors.
Specialist scientific and clinical assessors, with expertise in the relevant discipline of practice, conduct a thorough evaluation of all factors in the laboratory that affect the production of test data, including:
- technical competence of staff;
- validity and appropriateness of test methods, including pre- and post-analytical elements such as sample collection and reporting;
- sample quality, including patient identification, handling and transport to maintain sample integrity;
- a review of the history relating to previous patient results and any known clinical diagnoses;
- procedures relating to the use of “referral laboratories” such as specialised testing centres for specific diseases;
- traceability of measurements and calibrations to relevant standards;
- suitability, calibration and maintenance of test equipment;
- testing environment;
- quality assurance of test data;
- acceptable turnaround time;
- application of appropriate ethical values.
ISO 15189 is based on ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories) and ISO 9001 ( Quality management systems – Requirements). It therefore incorporates the quality systems elements addressed in ISO 9001 certification, as well as the general requirements of a testing laboratory. Accreditation to ISO 15189 places five additional critical criteria on medical laboratories which include:
- providing advice on the type of sample, and testing that may be required;
- interacting with clinical staff by placing a responsibility on the laboratory to liaise with clinicians who refer patient samples for testing about the quality of their service;
- providing opinions on results of testing in relation to diagnosis and patient care;
- collecting samples or if not, providing information on collection procedures, sample containers and sample volumes;
- and ethical practice – first duty is to the patient, not to the "customer".
These laboratories will also be required to participate in regular proficiency testing programs (known as external quality assurance programs or EQAS) as an on-going demonstration of their competence. -
ISO 15189 Laboratory Accreditation versus ISO 9001 Certification
-
The ISO 9001 standard is widely used in manufacturing and service organisations to evaluatetheir system for managing the quality of their product or service. Certification of an organisation’s quality management system against ISO 9001 confirms the compliance of the management system to this standard.
ISO 15189 accreditation on the other hand provides recognition of the medical laboratory’s competence including both the management system and technical practice.
Whilst medical laboratories may be certified to ISO 9001, such certification does not make any statement aboutthe technical competence of a laboratory. -
What are the Benefits of Accreditation?
Accreditation is an enabler of quality and a core component of good clinical management; it ispatient-focused, impartial, objective, and operates within a peer review model. It provides manybenefits such as those detailed below.
For Healthcare Regulators
The need to drive up the quality of care for patients, whilst delivering efficiency and productivity, is a key principle for regulators of healthcare services. Accreditation can be used as a tool to support the commissioning or specification of medical laboratory services that are technically competent, safe and reliable, and that continually improve the experience for patients by:- providing an independent assurance of quality and safety that supports world-class;
- decisions on how to deliver better care and value for patients;
- providing a mechanism for measuring quality improvement;
- supporting consistency in the quality of care;
- and encouraging innovation.
For Patients
Accreditation requires that the laboratory assesses the value and relevance of the testing in relation to the patient’s clinical management.
It demonstrates that medical laboratories comply with an international standard, confirming that:- there is consistency in the quality of care;
- the service has up-to-date-technologies and its procedures and techniques reflect current best practice;
- staff providing the service are competent to undertake the tasks they perform.
For Medical Laboratories
Accreditation provides proof that a laboratory complies with best practice. It also offers authoritative assurance of the technical competence of a laboratory to undertake specified analysis or measurements according to validated methods. Accreditation:- provides an opportunity for external perspectives on the laboratory’s practice;
- can prevent the unnecessary duplication of information gathering on performance often required by regulatory bodies;
- encourages the sharing of best practice;
- stimulates innovation;
- reduces risk;
- and provides international recognition.
How to find an Accredited Laboratory?
There are currently over 2200 medical laboratories worldwide accredited to ISO15189. These laboratories usually issue reports bearing some type of symbol or endorsement indicating their accreditation; however, the scope of accreditation should be checked, and should be supplied by the laboratory upon request.
Accreditation bodies in many economies publish lists or directories of the laboratories they haveaccredited, together with laboratories’ contact details and information on their testing capabilities.
If necessary, you can contact the accreditation body and find out further information. To find out if your economy has one or more laboratory accreditation bodies involved in accrediting medical laboratories, visit the website of the International Laboratory Accreditation Cooperation (ILAC) at www.ilac.org and use the directory of laboratory accreditation bodies available on this website. You will also find directories of accredited laboratories for many economies on this website.LxBIO is accredited by Healthcare section in compliance with ISO 15189 standard and COFRAC rules of application under n° 8-2529 for medical biology analyses activities .
The activities covered and the validity of accreditation are stipulated in the accreditation certificate in force which has been issued with it.
During this period, the laboratory undertakes to abide at all the times by the requirements of accreditation.-

Through a system of international agreements, accredited laboratories receive a form of international recognition which allows their data to be more readily accepted in overseas markets. Such international agreements, called mutual recognition arrangements (MRAs), are crucial in enabling test data to be accepted between different economies.
Over 70 accreditation bodies have signed a multi-lateral mutual recognition agreement called the ILAC Arrangement. Full details for the ILAC Arrangement and the list of signatories can be found on the ILAC website at www.ilac.org.More information about ILAC :
ILAC is the peak international authority on laboratory accreditation, with a membership consisting of accreditation bodies and stakeholder organisations throughout the world. It is involved with the development of laboratory accreditation practices and procedures, the promotion of laboratory accreditation as a trade facilitation tool, the assistance of developing accreditation systems, and the recognition of competent test and calibration facilities around the globe. ILAC actively cooperates with other relevant international bodies in pursuing these aims.
