Why NABL is Important?
Published 22 Apr 2025

The significance of NABL lies in the credibility it gives to the test reports generated by your lab. By obtaining NABL accreditation, your lab gets assured by the concerned authorities that the lab functions according to international standards (like ISO 15189:2022) and gives assurance to patients and doctors that the lab is credible.
NABL accreditation enhances the lab’s credibility, improves the confidence level of doctors, patients and the lab’s reputation in the market. It helps the lab gain government partnerships, health insurance panels and institutional referrals.

What is NABL Accreditation?
NABL is a constituent board of the Quality Council of India (QCI) and is the national accreditation body for testing and calibration laboratories.
NABL accreditation is a validation of a laboratory’s capability to perform specific tests, calibrations, and measurements.
For medical laboratories, NABL has the requirement of ISO 15189:2022, which provides requirements for quality and competence in medical laboratories.
What are the advantages of NABL accreditation?
NABL accreditation helps medical laboratories, diagnostic centers and healthcare organizations to-
- Achieve accuracy and reliability in their test results
- Increase the level of confidence of doctors
- Build credibility of the lab in the market
These practices assist laboratories in error detection, performance monitoring and improvement of the reliability of test results.
2. Patient Trust and Confidence
Laboratory reports are the means for patients to gain knowledge about their health condition.
NABL accreditation is recognition of a laboratory’s performance against various quality and technical requirements.
This fosters trust and confidence among patients using diagnostic laboratory services.
3. Doctor Confidence
Laboratory results form the basis of clinical decisions.
Depending upon the reports, healthcare professionals take necessary clinical decisions to manage a patient’s health condition and administer appropriate treatment.
NABL accreditation validates competence of laboratory’s testing processes.
4. Government and Hospital Opportunities
Various government schemes, hospitals, corporate health care programs and health insurance companies have provisions to provide diagnostic services only through NABL accredited laboratories.
NABL accreditation provides opportunity to eligible laboratories to extend their diagnostic services to the above mentioned categories of clients.
However, eligibility criteria would vary based on the government scheme, hospital, corporate health care program or insurance company.
5. Improvement of Laboratory Management
NABL accreditation facilitates laboratories to refine their management systems, procedures and practices for calibration and maintenance of instruments, documentation, staff training, internal audits, management reviews, quality control and assurance.
Practicing these helps in improvement of laboratory services and decrease unnecessary errors.
6. Continuous Improvement
NABL accredited laboratories are obligated to continuously benchmark their performance and identify improvement opportunities.
In addition, internal audits, quality indicators and corrective actions help laboratories to identify problems and improve their processes and systems.
Continuous improvement forms the foundation of quality management in laboratories.
The role of ISO 15189:2022 in NABL Accreditation
ISO 15189:2022 specifies requirements of quality and competency for medical laboratory services.
It encompasses both managerial and technical aspects.
Important components include:
- Collection, handling, and processing of samples
- Maintenance and calibration of equipment
- Internal Quality Control (IQC)
- External Quality Assessment (EQA)
- Staff training and proficiency
- Method validation and verification
- Laboratory information management
- Internal audits and management reviews
Incorporating these components allows the laboratories to build and institutionalize practices to ensure consistency in their testing activities.
NABL expects medical laboratories seeking accreditation to adhere to the criteria specific to them.

NABL assessors review the findings of the assessment, and make a decision on accreditation.
Common Issues During NABL Assessment
Challenges are often faced by a laboratory in preparation for accreditation.
- Inadequate Documentation: Outdated, or completely missing records and documents.
- Poor Quality Control: Tests are performed without prior monitoring of the laboratory’s performance.
- Staff Training: Employees may not be fully aware of the requirements applied to the services.
