NABL Accreditation: Importance & Benefits [2026]

Every testing, medical and calibration laboratory will benefit from NABL accreditation in India. It is a regulatory body that certifies labs based on national and international standards, so labs follow the universally established procedures and techniques. NABL certification is not mandatory. But those with accreditation enjoy trust from customers and a global recognition.

Laboratories that seek to be the frontline of quality healthcare must get NABL accreditation to ensure they are on the correct path. It is also about upgrading equipment, training personnel, adapting to evolving testing procedures. We will look at the “Why” of NABL certification in this read along with some other aspects.

What is NABL Accreditation

NABL full form - NABL (National Accreditation Board for Labs) accreditation ensures that laboratories follow standardized procedures, maintain quality, and gain trust and recognition.

NABL’s full form is National Accreditation Board for Testing and Calibration Laboratories. It is a regulatory body in India that certifies medical and calibration laboratories regarding adherence to global and national standards in healthcare. Before delivering medical testing services, a medical laboratory in India must receive NABL certification.

NABL, through a series of steps, examines the testing procedures, equipment calibration, and various standards of a medical lab to either accept or refuse accreditation. In reality, NABL accreditation is not mandatory.

But medical labs seeking to leave a footprint in the healthcare sector and reach global markets must receive NABL certification. Labs with NABL certification find a place in their database for people from across the world to verify and learn about certified labs for testing and calibration.

NABL Accreditation Eligibility

NABL provides accreditation to the following laboratories:

• Testing Calibration laboratories as per ISO/IEC 17025.
• Medical testing laboratories as per ISO 15189.
• Proficiency Testing Providers (PTP) as per ISO/IEC 17043.
• Reference Material Producers (RMP) as per ISO 17034.

NABL Accreditation for Medical Laboratories

The Importance of NABL Accreditation in India

Capability Assessment: NABL accreditation is primarily an assessment of a lab’s capacity to deliver standardised and reliable medical testing services. NABL accreditation process certifies everything from testing procedures, personnel, equipment to lab environments, before certifying a lab’s expertise to furnish precise and trustworthy test outcomes.

Regulatory Compliance: Medical industry has some of the critical functionalities in society. It has to safeguard the lives of people. To ensure optimal healthcare, medical laboratories must be compliant with global regulations. NABL accreditation in India performs the task of accrediting medical labs in accordance with national and international regulations.

Continuous Refinement: Maintaining NABL accreditation requires a perpetual journey of advancement. Post-accreditation, laboratories undergo routine surveillance assessments to ensure their adherence to standards. So labs have to maintain a constant refinement in processes, systems, and services to keep up with the latest technology and equipment.

International Recognition: NABL holds membership in the International Laboratory Accreditation Cooperation (ILAC) and Asia Pacific Laboratory Accreditation Cooperation (APLAC) Mutual Recognition Arrangements. The World Health Organisation (WHO) also considers NABL certification. As such, NABL accredited labs enjoy global representation.

Quality Control: NABL accreditation standards are derived from the best healthcare systems in the world with strong quality control. So labs with NABL certification directly indicate compliance with rigorous international quality standards. NABL accredited labs possess the proficiency to deliver precise and dependable test results.

Increased Business: NABL accreditation process ensures smoother acceptance of a lab’s data and results in foreign markets. It reduces costs for manufacturers and exporters. They also avoid or minimise retesting expenses abroad thanks to accreditation. Moreover, people can across the world find access to a lab’s services.

NABL Proficiency Tests: Many labs operate independently, lacking chances to compare their data with others. This isolation poses risks like errors or biases in lab data, differing from similar labs' data. Proficiency testing allows such comparisons and offers an independent assessment of lab data against reference values or similar labs' performance. Results confirm satisfactory performance or flag potential issues needing investigation within the lab.

Professional Development: The process of achieving and maintaining NABL accreditation encourages continuous professional development among laboratory staff. It fosters a culture of learning, training, and skill enhancement among medical labs. Because, they have to meet evolving standards and technological advancements in the field of medical testing.

Support for Research and Innovation: Accredited laboratories often play a vital role in medical research and innovation. NABL accreditation provides a framework to conduct reliable and reproducible research studies in medical labs, which contributes to advancements in medical science and technology.

Government Recognition and Support: NABL accredited labs often enjoy government contracts, grants, and funding in healthcare-related projects. Government agencies provide incentives and support to accredited facilities.

Contribution to National Healthcare Infrastructure: NABL accredited labs play a crucial role in strengthening the national healthcare infrastructure. By ensuring the quality and reliability of diagnostic services, NABL-accredited labs contribute to early disease detection, timely treatment, and overall improvement in public health outcomes.

NABL Internal Audit Checklist 15189:2012

ISO 15189:2012 standard defines the document checklist for NABL accreditation. Laboratories must ready the below documentation for that.

• Name and location details of the laboratory.
• Legal identity.
• Type of Laboratory.
• Details on other accreditation.
• Information on disciplines applied.
• Scope of the Laboratory.
• Required details of senior management.
• Proposed personnel to release the results.
• Organisation chart of the Laboratory.
• Details of staff.
• List of equipment/ Reference materials/ reference standards.
• Internal audit.
• Management Review.
• PT/ ILC.
• Any general points.

NABL Accreditation Validity

NABL accredited labs are known as Conformity Assessment Bodies (CABs). Every CAB must undergo reassessment every 2 years to maintain NABL certification. The reason is simple: Technology, tools, lab procedures will go through massive changes in 2 years. To assure testing accuracy, they have to upgrade themselves.

NABL reassessment ensures that labs are following the latest standards. A CAB must apply for NABL reassessment 6 months before the expiry of their accreditation. Such CABs must contact the NABL’s Information Cell or email them at info@nabl.qcin.org.

Conclusion

NABL accreditation is the gold standard for medical laboratories in India, validating their adherence to stringent national and global benchmarks. The rigorous evaluation process challenges labs to continuously upgrade infrastructure, processes and workforce competencies. Achieving NABL status is the way for enhanced credibility, new business prospects, research funding and international collaborations. As industry standards and technologies evolve, NABL-accredited labs will consistently raise the bar for medical testing and diagnosis in the country.
