What is the Process to Get a NABL Certificate?

To obtain a NABL certificate, adequate documentation, training, internal audits, and compliance with the applicable requirements are mandatory.

Process of NABL Accreditation

The process of NABL accreditation consists of several important steps.

The First Step: Understand NABL Standards and Requirements

The medical laboratories need to identify the applicable standard and determine the scope of testing for which accreditation is sought.

The medical laboratories follow the standard ISO 15189:2022 along with the applicable NABL requirements.

These include:

  • Internal Quality Control (IQC)
  • External Quality Assessment (EQA)
  • Calibration of Equipment
  • Verification or Validation of Methods, as appropriate
  • Staff Competency Assessment

Step 5: Conduct Internal Audit and Management Review

The laboratory performs internal audits and management reviews as part of its accreditation exercise.

These activities help in identifying issues and evaluating the effectiveness of the quality management system.

Step 6: Submit the NABL Application

The laboratory applies for accreditation to NABL via the official NABL portal, mentioning the proposed scope and submitting supporting information, if any.

Step 7: NABL Assessment

Assessors appointed by NABL evaluate the laboratory’s technical competence and quality management system, as well as review the laboratory’s processes and documentation associated with testing.

Step 8: Corrective Actions and Accreditation Decision

Following the assessment, should there be any nonconformities, the laboratory is required to take appropriate corrective actions and submit them to NABL for consideration.

Once the nonconformities are determined to be satisfactory, NABL issues the laboratory’s accreditation.

The laboratory is presented with its certificate and the approved scope of accreditation.

Documents Required for a NABL Certificate

Accreditation helps laboratories gain and retain confidence in the services they provide.

Demonstrating compliance with the accreditation requirements, to a large extent, is dependent on effective documentation.

Some of the important documents and records are as follows:

  • Quality Manual and Policies
  • Standard Operating Procedures
  • Staff qualifications
  • Staff Competency
  • Calibration of Equipment
  • IQC and EQA
  • Internal Audits
  • Management Reviews
  • Corrective Actions
  • Method Validation
  • Proposed Scope of Accreditation

Laboratories should ensure these documents are effective and appropriately implemented.

  • Clinical Biochemistry

During this period, the laboratory has to maintain its quality management system and its technical competence.

The laboratory must carry out the required surveillance activities and assessment to maintain accreditation.
