Are you intending to set up a testing lab or industrial testing facility? Well, that is an ideal step, given the demand for quality assurance among diverse industries. However, if you want to take this business one step further, you can’t afford to overlook NABL Accreditation. Although getting it is not mandatory for all industries, its presence can make a huge difference in how you market your lab and drive growth. Let’s learn about NABL certification and how you can apply for it in 2026.
What Exactly is Required to Secure the NABL Accreditation?
Calibration facilities and medical labs must adhere to the following requirements to qualify for NABL Accreditation.
- They must comply with ISO/IEC 17025:2017
- They must comply with ISO 15189:2022.
- They must be a legal entity registered as either a Private Limited Company or an LLP)
- They must have implemented Standard Operating Procedures (SOPs) detailing everyday laboratory operations, document control, and data integrity.
- They must have a designated Quality Manager with a specialization in ISO standards and internal auditing.
- They must get all their analytical instruments certified by a NABL-accredited calibration laboratory.
- The lab must have undergone a Proficiency Testing program or an External Quality Assessment Scheme (EQAS).
- The lab must have completed at least one cycle of internal audit.
Step-by-Step NABL Accreditation Process
The journey toward NABL accreditation is systematic and heavily scrutinized. It transitions through structural prep work into multi-tiered formal assessments.
- Gap Analysis: Evaluate your laboratory’s current infrastructure, equipment status, and staff qualifications against the baseline requirements of the relevant ISO standard.
- Documentation & Training: Draft your specialized Quality Manuals, SOPs, and registers. Send key technical and managerial staff to mandatory ISO internal auditor workshops.
- System Implementation & Testing: Run regular laboratory testing under the newly established QMS for a minimum of 2 to 3 months. Complete your PT/EQAS testing and execute your pre-application Internal Audit and MRM.
- Application Submission: Submit your comprehensive application online through the centralized NABL portal[1] alongside the required application fee, equipment inventory, and proof of consultant disclosure (if applicable).
- Pre-Assessment / Document Review: A lead assessor appointed by NABL scrutinizes your documentation and the adequacy of facilities. Any initial adequacy gaps or queries must be addressed online.
- Final On-Site (or Hybrid) Assessment: A specialized technical team conducts an exhaustive on-site audit. They evaluate technical competence, staff testing capabilities, instrument calibrations, and sample handling pipelines.
- Closure of Non-Conformities (NCs): The assessment team will issue a list of Non-Conformities (NCs). The laboratory is typically given a fixed window (up to 30 days) to implement Corrective and Preventive Actions (CAPA) and upload evidence of resolution to the portal.
- Grant of Accreditation: Upon successful verification of NC closures, the NABL Accreditation Committee reviews the file and issues your formal Certificate of Registration.
Cost and Fee Structure
NABL operates as a self-financing body and structures its charges based on the scale of the laboratory, the number of disciplines applied for, and the operational categories.
Core Official NABL Fee Schedule
| Laboratory Type / Scope | Application Fee (Per Discipline/Product Group) |
| Testing Laboratories (Chemical, Biological, Mechanical, etc.) | ₹11,000 |
| Calibration Laboratories (Electro-Technical, Thermal, Fluid Flow) | ₹11,000 to ₹33,000 (depending on parameters) |
| Integrated Assessment Labs (e.g., FSSAI, APEDA approvals) | ₹25,000 |
| Forensic & Software Testing Laboratories | ₹44,000 |
| Medical Testing Laboratories (Scale-based by patient load/day) | |
| • Micro Labs (Up to 25 patients/day) | ₹6,000 |
| • Mini Labs (26 to 50 patients/day) | ₹10,000 |
| • Small Labs (51 to 100 patients/day) | ₹18,700 |
| • Medium Labs (101 to 400 patients/day) | ₹44,000 |
| • Large / Very Large Labs (401 to 1000+ patients/day) | ₹1,10,000 to ₹2,20,000 |
Beyond the Official Fees: Indirect Costs to Budget
While the direct government portal fees are fixed, the macro cost of securing NABL certification involves secondary operational investments:
- Assessment Expenses: The applicant laboratory must cover the actual travel, boarding, and lodging costs of the NABL assessment team during on-site evaluations.
- Equipment Calibration: Getting all your standard lab hardware calibrated by third-party accredited agencies can range from ₹15,000 to over ₹1,00,000, depending on complexity.
- PT/EQAS Charges: Enrolling in official proficiency testing programs run by specialized providers.
- Infrastructure & Training Upgrades: Upgrading physical testing layouts, purchasing certified reference materials, and enrolling the Quality Manager in mandatory training courses.
NABL has streamlined its certification lifecycle. The accreditation validity spans 4 years, supplemented by an annual automated surveillance or physical audit cycle to ensure your quality systems remain fully uncompromised.

Frequently Asked Questions
Q: Can a proprietorship firm apply for NABL accreditation?
A: Yes, they can apply for NABL approvals.
Q: How long does the entire NABL approval process take from start to finish?
A: A laboratory with a well-prepared Quality Management System (QMS) usually secures accreditation within 4 to 6 months. For facilities starting from scratch, the timeline spans 9 to 12 months.
Q: Are NABL test reports legally valid outside of India?
A: Yes. Because NABL is a full member and signatory to the global ILAC Mutual Recognition Arrangement (MRA), international buyers and overseas customs authorities accept NABL-accredited test reports worldwide.
Q: Can a person get NABL accreditation?
A: No. NABL only accredits Conformity Assessment Bodies (CABs), such as structural testing laboratories, calibration units, or medical diagnostic facilities. It does not accredit individuals.
Q: What happens if a laboratory fails to resolve its Non-Conformities (NCs) within 30 days?
A: If a laboratory fails to submit acceptable Corrective and Preventive Actions (CAPA) within the mandatory 30-day window, NABL can reject the application, which forces the lab to file a fresh application with new fees.
