How to Prepare for NABL Audit - A Complete Readiness Checklist
Published 11 months ago

NABL (National Accreditation Board for Testing and Calibration Laboratories) accreditation is a symbol of quality, accuracy, and trust. It ensures that your laboratory meets international standards for testing and reporting.
At Qualityveda, we simplify the entire NABL journey into seven practical steps. Here’s a clear roadmap that shows how your lab can prepare effectively for a successful NABL audit.
Step 1: Gap Analysis of the Laboratory
The first step is a one-day
comprehensive assessment of your laboratory.
During this gap analysis, we evaluate your lab’s current status - checking
every key aspect, including:
- Legal and statutory documents
- Infrastructure and facility suitability
- Staff qualification and competence
- Equipment calibration and maintenance
- Availability and quality of reagents and materials
This step helps us identify where your lab stands today and what improvements are required to meet NABL standards.
Step 2: Gap Closure & Scope Finalization
Once all gaps are identified, the next step is to close those gaps through proper corrective actions. At this stage, we also finalize the scope of accreditation - deciding which tests and parameters your lab will apply for under NABL.
This ensures clarity on the exact area of focus before starting the documentation process.
Step 3: Documentation & Staff Training
A strong documentation system is the foundation of NABL compliance. We help your lab develop all required documents such as:
- Quality Manual
- SOPs (Standard Operating Procedures)
- Equipment Logs
- Quality Records
Along with this, our team conducts training sessions for your staff so they fully understand their roles, responsibilities, and documentation requirements as per ISO 15189:2022.
Step 4: NABL Application Submission
After documentation and training
are completed, the lab is ready to submit the NABL application.
This includes uploading required documents, fee submission, and initial
communication with NABL officials.
Qualityveda assists throughout this process to make sure all forms and data are accurate, avoiding delays or rejections.
Step 5: Conducting Internal Audit
Before the official NABL assessment, it’s important to
perform an Internal Audit.
This internal check ensures that:
- All documents are in place,
- Processes are being followed correctly, and
- Staff is fully aware of audit procedures.
This mock audit helps your team gain confidence and identify any last-minute improvements before the real assessment.
Step 6: Assessment Scheduling & Execution
Next, NABL will assign a date for
the on-site assessment.
During this visit, NABL assessors evaluate your lab’s technical competence,
documentation, staff interviews, and overall implementation of ISO 15189:2022.
Our experts at Qualityveda stay connected throughout this stage to help coordinate and ensure a smooth audit experience.
Step 7: NC (Non-Conformity) Closure & Certification
After the assessment, NABL may
raise some Non-Conformities (NCs) - areas that need correction or
improvement.
Once you close all NCs with proper corrective actions and submit the evidence,
your lab receives the NABL Accreditation Certificate.
Congratulations! Your lab is now recognized as a quality-driven, globally compliant testing facility.
In summary:
NABL accreditation is not just about documentation - it’s about building a
culture of quality in your lab.
By following these 7 stages with proper planning and expert support, you can
achieve accreditation smoothly and sustain it long-term.
