How to Choose the Right ISO/IEC 17025 and ISO 15189 Accreditation Body

 

 

For organizations involved in testing, calibration, and medical laboratory services, accreditation is more than a formal requirement. It demonstrates technical competence, operational reliability, and a commitment to internationally recognized quality standards. Choosing the right accreditation body is therefore an important decision that can influence a laboratory’s credibility, regulatory compliance, and acceptance of its results.

This guide explains how to select a suitable accreditation body for ISO/IEC 17025 and ISO 15189, highlighting the essential factors laboratories should evaluate before beginning the accreditation process.

Understanding ISO/IEC 17025 and ISO 15189

Before selecting an accreditation body, it is important to understand the purpose and scope of the two standards.

ISO/IEC 17025 specifies the general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories. It applies to laboratories performing activities such as chemical analysis, microbiological testing, mechanical testing, electrical testing, and calibration.

ISO 15189 accreditation establishes requirements for the quality and competence of medical laboratories. It focuses on laboratory processes, technical competence, and quality management to support reliable examination results and patient care.

Although both standards emphasize quality and technical competence, they address different laboratory activities. Therefore, laboratories should select an accreditation body appropriate to their specific services and accreditation requirements.

Why Is Choosing the Right Accreditation Body Important?

An accreditation body assesses whether a laboratory meets the applicable requirements of an international standard through documented evaluations, on-site assessments, and ongoing monitoring.

Selecting an appropriate and recognized accreditation body can help laboratories:

Demonstrate technical competence and reliable laboratory operations.
Build confidence among customers, healthcare professionals, regulators, and business partners.
Support compliance with applicable regulatory and contractual requirements.
Improve quality management systems and operational consistency.
Strengthen the credibility and acceptance of laboratory reports.
Identify opportunities for continuous improvement.

Conversely, choosing an unsuitable or insufficiently recognized accreditation body may limit the acceptance of laboratory results and create unnecessary financial and reputational risks.

Key Factors to Consider When Selecting an Accreditation Body

1. Verify International Recognition

International recognition is one of the most important considerations when choosing an accreditation body. Laboratories should verify the body’s recognition status, relevant scope, and participation in applicable mutual recognition arrangements.

For organizations seeking ISO/IEC 17025 accreditation in India, international recognition may help demonstrate the credibility of laboratory results to overseas customers and business partners.

However, recognition should never be assumed. Laboratories should verify the accreditation body’s current status and confirm that the relevant technical scope is covered by applicable recognition arrangements.

2. Evaluate the Scope of Accreditation

Accreditation bodies may differ in their technical expertise and the scopes they are authorized to assess. Laboratories should ensure that the selected body can assess their specific activities.

These may include:

Chemical and microbiological testing.
Mechanical and electrical testing.
Calibration services.
Clinical and medical laboratory examinations.
Specialized diagnostic testing.

For laboratories pursuing ISO 15189 accreditation, it is particularly important to confirm that the accreditation body has the appropriate competence and scope for medical laboratory services.

Selecting a body with relevant technical expertise helps ensure that assessments are appropriate to the laboratory’s actual operations.

3. Assess Technical Competence and Impartiality

The competence and impartiality of assessors directly influence the quality and credibility of the accreditation process.

Laboratories should evaluate whether the accreditation body uses qualified assessors with relevant technical knowledge, professional experience, and an understanding of the applicable standard.

Impartiality is equally important. The accreditation body should operate independently and manage potential conflicts of interest effectively. This helps maintain confidence in assessment decisions and protects the integrity of the accreditation process.

4. Understand the Accreditation Process and Costs

A reliable accreditation body should provide clear information about its application procedures, assessment stages, timelines, fees, surveillance requirements, and reassessment processes.

Before making a decision, laboratories should request details about:

Application and documentation requirements.
Initial assessment procedures.
Assessment and accreditation fees.
Corrective action and follow-up processes.
Surveillance assessments and reassessments.
Complaint and appeal mechanisms.

Transparent communication enables laboratories to plan their resources, prepare the necessary documentation, and understand their responsibilities throughout the accreditation journey.

This is particularly important for organizations pursuing ISO/IEC 17025 or ISO 15189 accreditation, as the process requires ongoing commitment rather than a one-time evaluation.

5. Look for Educational Resources and Awareness Programs

Accreditation bodies must maintain their independence and should not compromise impartiality by providing consultancy that creates a conflict of interest. However, access to relevant educational resources can help laboratories understand applicable requirements.

Laboratories may benefit from standard-awareness programs, publicly available guidance documents, technical information sessions, and training opportunities.

Organizations such as the Federation for Development of Accreditation Services (FDAS – India) may be considered for relevant information about laboratory quality and accreditation. Before proceeding, laboratories should independently verify the organization’s current recognition status, applicable scope, and authority to grant accreditation for the standard concerned.

6. Check National Regulatory Requirements

Accreditation requirements can vary according to the industry, jurisdiction, and intended use of laboratory results.

Laboratories operating in healthcare, environmental monitoring, food safety, pharmaceuticals, and industrial testing should determine whether relevant regulators, customers, or contracts require accreditation from a particular body.

For medical laboratories, choosing an appropriately recognized accreditation body can help strengthen confidence among healthcare professionals, patients, and other stakeholders.

Organizations seeking clinical lab accreditation or medical lab accreditation should also confirm that the selected body’s scope and recognition meet the requirements applicable to their services.

7. Consider Long-Term Credibility and Reliability

Accreditation is an ongoing commitment to maintaining technical competence and an effective quality management system. Laboratories must continue meeting applicable requirements through routine monitoring, corrective actions, surveillance assessments, and reassessments.

Before selecting an accreditation body, consider its professional reputation, consistency, communication practices, assessment procedures, and commitment to impartial decision-making.

A suitable accreditation partner should provide a clear framework for maintaining accreditation and help laboratories understand their continuing obligations without compromising the independence of the assessment process.

Organizations such as the Federation for Development of Accreditation Services (FDASIndia) can be researched as part of this evaluation. Laboratories should verify the organization’s current credentials and accreditation authority before making a final decision.

Common Mistakes to Avoid When Choosing an Accreditation Body

Laboratories should avoid the following mistakes when evaluating accreditation options:

Choosing based only on cost: Lower fees should not outweigh recognition, competence, and credibility.
Ignoring recognition status: Always verify the accreditation body’s current standing and applicable recognition arrangements.
Overlooking technical expertise: Confirm that the body can assess the laboratory’s specific testing, calibration, or medical examination activities.
Assuming all accreditation bodies are equivalent: Their recognition, scope, expertise, and assessment procedures may differ.
Neglecting ongoing requirements: Understand the surveillance, reassessment, and continual compliance obligations before applying.
Failing to verify credentials: Check the body’s official status and authority rather than relying solely on promotional claims.

Avoiding these mistakes can help laboratories make informed decisions and protect the long-term value of their accreditation efforts.
