For organizations involved in testing, calibration, or medical laboratory services, accreditation is more than a formal requirement—it is a mark of technical competence, credibility, and global acceptance. Selecting the right accreditation body plays a crucial role in ensuring that laboratory results are accurate, reliable, and internationally recognized. This guide explains how to choose an appropriate ISO/IEC 17025 and ISO 15189 accreditation body, while highlighting key factors that laboratories should carefully evaluate before making a decision.
Understanding ISO/IEC 17025 and ISO 15189
ISO/IEC 17025 is the international standard that specifies the general requirements for the competence of testing and calibration laboratories. It applies to laboratories performing chemical, biological, mechanical, electrical, or calibration activities, regardless of size or sector.
ISO 15189, on the other hand, is specifically designed for medical laboratories. It focuses on quality management systems and technical competence to ensure reliable patient test results.
Both standards help laboratories demonstrate consistency, impartiality, and technical excellence. However, achieving compliance depends significantly on the expertise and credibility of the laboratory accreditation body granting the certification.
Why Choosing the Right Accreditation Body Matters
An accreditation body evaluates whether a laboratory meets international standards through assessments, audits, and continuous surveillance. The right accreditation body ensures:
- Global recognition of test and calibration results
- Confidence among clients, regulators, and stakeholders
- Compliance with regulatory and contractual requirements
- Continuous improvement in laboratory operations
Choosing an unsuitable or non-recognized body can result in limited acceptance of reports, reputational risk, and unnecessary costs.
Key Factors to Consider When Selecting an Accreditation Body
-
International Recognition and Acceptance
A credible accreditation body should operate in alignment with international frameworks and mutual recognition arrangements. This ensures that reports issued by accredited laboratories are accepted across borders, which is especially important for export-oriented testing and calibration services.
For organizations seeking ISO/IEC 17025 accreditation in India, international recognition helps laboratories compete in global markets and comply with overseas regulatory requirements.
- Scope of Accreditation
Not all accreditation bodies cover the same technical scopes. Laboratories should confirm that the accreditation body has experience and authorization in their specific field, whether chemical testing, mechanical calibration, microbiology, or medical diagnostics, under ISO 15189 accreditation.
A competent laboratory accreditation body will have assessors with technical expertise relevant to the laboratory’s activities.
- Assessment Competence and Impartiality
The quality of assessors directly affects the value of accreditation. Experienced, well-trained assessors can provide meaningful insights beyond compliance, helping laboratories strengthen their systems.
Impartiality is equally critical. Accreditation bodies must operate independently, without conflicts of interest, to maintain trust and credibility in the accreditation process.
- Transparency of the Accreditation Process
A reliable accreditation body clearly explains its procedures, timelines, costs, and assessment methodology. Laboratories should look for transparent documentation covering application processes, surveillance audits, reassessments, and complaint handling.
Clear communication reduces uncertainty and helps organizations prepare effectively for assessments under ISO IEC 17025 or ISO 15189.
- Support and Guidance Without Consultancy
While accreditation bodies must not act as consultants, many provide guidance documents, interpretations of standards, and awareness programs. These resources help laboratories understand standard requirements without compromising impartiality.
Institutions such as the Federation for Development of Accreditation Services (FDAS – India) emphasize awareness-building and capacity development while maintaining strict independence during assessments.
- National and Regulatory Relevance
In some sectors, regulators or government bodies may prefer or require accreditation from specific bodies. Laboratories operating in healthcare, environmental testing, or food safety should ensure the chosen accreditation body aligns with national regulations and sector-specific expectations.
For medical laboratories, selecting a recognized ISO 15189 body ensures trust among clinicians, patients, and healthcare authorities.
- Long-Term Partnership and Credibility
Accreditation is not a one-time event. Surveillance audits, reassessments, and continual improvement are part of the journey. Laboratories should choose an accreditation body that demonstrates long-term commitment, professional integrity, and consistent service quality.
A well-established organization like the Federation for Development of Accreditation Services (FDAS – India) focuses on strengthening quality infrastructure while supporting laboratories in maintaining international benchmarks.
Common Mistakes to Avoid
- Choosing an accreditation body solely based on lower fees
- Ignoring international recognition or acceptance
- Overlooking assessor competence in specialized testing areas
- Assuming all accreditation bodies offer the same value
Avoiding these pitfalls helps laboratories maximize the return on their accreditation investment.

Final Thoughts
Selecting the right ISO/IEC 17025 or ISO 15189 accreditation body is a strategic decision that directly impacts a laboratory’s credibility, market acceptance, and operational excellence. By evaluating recognition, technical competence, transparency, and long-term reliability, organizations can make informed choices that support sustainable growth.
Whether pursuing ISO/IEC 17025 accreditation in India or medical laboratory accreditation under ISO 15189, working with a credible and impartial laboratory accreditation body ensures that test and calibration results stand up to national and international scrutiny. Ultimately, the right accreditation partner reinforces trust among clients, regulators, and the global marketplace. clinical lab accreditation or medical lab accreditation
