Understanding NABL 15189: The Key to Quality Medical Laboratory Accreditation 🧪✅

In a healthcare world where accuracy, reliability, and credibility are non-negotiable, NABL 15189 accreditation has become the gold standard for medical laboratories in India and globally. But what exactly is it, and how can your lab achieve it?

Let’s break it down for healthcare professionals, pathologists, and lab managers looking to build trust and meet international standards.


🔍 What is NABL 15189?

NABL 15189 refers to the National Accreditation Board for Testing and Calibration Laboratories (NABL) standard based on ISO 15189:2022—an international benchmark for medical laboratories.

This accreditation ensures:

  • Reliable test results
  • Standardized lab processes
  • Improved patient safety
  • International recognition of results

📌 It’s a must-have for labs looking to stand out in quality and credibility.


🎯 Why NABL 15189 Accreditation Matters

✅ Builds Patient Confidence

Patients and doctors can trust your lab’s test reports, knowing they’re accurate and timely.

✅ Enhances Lab Efficiency

With clearly defined processes, your lab minimizes errors, retesting, and delays.

✅ Required for Empanelment

Many government and corporate health schemes require NABL accreditation for partnership.

✅ Opens International Doors

Get recognized by global partners, research institutions, and international organizations.


🧭 Key Requirements for NABL 15189

Here’s what your lab needs to implement:

1. Quality Management System (QMS)

Define and document all policies, processes, and procedures—from sample collection to result reporting.

2. Competent Personnel

Staff must be trained and qualified to handle tests and equipment per standard protocols.

3. Equipment Calibration and Maintenance

All instruments must be periodically maintained and traceable to national/international standards.

4. Internal & External Audits

Regular internal audits and participation in proficiency testing (PT) are essential for maintaining quality.

5. Risk Management

Identify and manage risks that can affect test outcomes, patient safety, or turnaround time.


🛠️ Step-by-Step: How to Get NABL Accredited

Step 1: Gap Assessment

Evaluate your current lab practices against NABL 15189 requirements.

Step 2: Documentation & SOPs

Develop Standard Operating Procedures (SOPs) aligned with QMS principles.

Step 3: Staff Training

Train your team on documentation, quality checks, and handling deviations.

Step 4: Internal Audit

Conduct a full audit to identify and correct non-conformities.

Step 5: Apply to NABL

Submit your application via NABL’s online portal along with required documents and fees.

Step 6: NABL Assessment Visit

NABL assessors visit your lab for a full on-site evaluation.

Step 7: Accreditation Grant

Upon successful review, you’ll receive a certificate valid for 2 years with periodic surveillance audits.


📌 Key Takeaways

  • NABL 15189 boosts your lab's trust, accuracy, and global standing.
  • It requires strategic planning, documentation, and team training.
  • Start small with a gap assessment and build step-by-step.

💡 Pro Tip: Use digital LIMS (Laboratory Information Management Systems) to automate and standardize your quality processes.
