NABL Accreditation for Pathology Labs — Complete 2025 Guide

A pathology laboratory seeking NABL accreditation in 2025 must comply with ISO 15189:2022 — the current standard for medical laboratory quality and competence.

Pathology and diagnostic laboratories in India face increasing pressure from insurance companies, government schemes, and referring physicians to demonstrate quality through NABL accreditation. This guide covers everything a pathology lab owner needs to know about achieving NABL accreditation in 2025.

Scope of NABL Accreditation for Pathology Labs

NABL accreditation for medical laboratories covers multiple disciplines. Your lab’s scope of accreditation defines which specific tests are covered. Common scopes include:

• Clinical Biochemistry: Blood glucose, lipid profile, liver function tests, kidney function tests, thyroid panel, etc.
• Haematology: CBC, ESR, peripheral smear, coagulation studies, etc.
• Clinical Pathology: Urine microscopy, stool examination, CSF analysis, etc.
• Microbiology: Culture and sensitivity, AFB smear, serology, etc.
• Histopathology and Cytology: Biopsy processing, FNAC, PAP smear, etc.

NABL Entry Level Accreditation

For smaller labs that are not yet ready for full NABL accreditation, NABL offers an Entry Level accreditation scheme that covers a more limited scope and has less stringent requirements. This is an excellent stepping stone for small pathology labs.
