NABL Accreditation for Laboratories

NABL Accreditation is the supreme, internationally recognized quality and technical competence recognition granted by the National Accreditation Board for Testing and Calibration Laboratories (NABL), an autonomous constituent board under the Quality Council of India (QCI). NABL accreditation is formally based on the stringent international standards ISO/IEC 17025:2017 (for testing and calibration laboratories) and ISO 15189:2022 (for medical diagnostic laboratories). It certifies that a laboratory possesses calibrated testing equipment, validated analytical methods, environmental testing controls, and technical personnel competent to generate scientifically precise, legally valid test results.

In India, achieving NABL accreditation is an absolute commercial and regulatory necessity for any testing, calibration, or medical diagnostic laboratory. Test reports issued by non-accredited laboratories are routinely rejected by government procurement agencies, judicial courts, environmental regulators (CPCB/SPCB), food safety authorities (FSSAI), and export customs authorities. Conversely, because NABL is a full signatory to the International Laboratory Accreditation Cooperation (ILAC) Mutual Recognition Arrangement (MRA), test reports generated by an NABL accredited laboratory in India are universally accepted by regulatory authorities and buyers in over 100 countries across the globe—eliminating the need for re-testing of exported goods.

At I-Pro Solutions, our elite team of NABL Lead Assessors, metrology specialists, and clinical quality consultants deliver comprehensive, turnkey advisory for NABL accreditation. We conduct rigorous laboratory gap assessments, draft your Quality Manual and Standard Operating Procedures (SOPs), perform Measurement of Uncertainty (MU) calculations, coordinate Inter-Laboratory Comparisons (ILC) and Proficiency Testing (PT), train your technical personnel, and guide your laboratory seamlessly through NABL pre-assessment and final on-site assessments—guaranteeing first-time accreditation success within 45 to 90 working days.

NABL Accreditation under ISO/IEC 17025:2017 or ISO 15189:2022 is applicable to all laboratories performing testing, calibration, or medical diagnostics, whether owned by government, private enterprises, universities, or industrial manufacturing plants. You are eligible and strongly advised to obtain NABL accreditation if your facility operates as: • Commercial Independent Testing Laboratories: Third-party testing labs conducting chemical, mechanical, electrical, biological, non-destructive testing (NDT), environmental (air/water/soil), or textile testing for commercial clients. • Calibration Laboratories: Metrology labs performing precision calibration of electro-technical, mechanical, thermal, optical, fluid flow, or radiological measuring instruments. • Medical & Clinical Diagnostic Laboratories: Pathology labs, clinical biochemistry centers, hematology labs, microbiology diagnostics, and molecular genetics testing facilities seeking ISO 15189 recognition. • Industrial In-House Quality Control (QC) Labs: Captive testing laboratories situated within manufacturing plants (steel mills, pharma factories, food processing plants, cement factories) testing raw materials and finished products for quality compliance. • Research & Academic Institution Laboratories: University analytical centers and R&D laboratories providing commercial testing or sponsored scientific research services. Applicability Note: NABL grants accreditation for specific scopes of testing or calibration (specific parameters, test methods, and ranges) rather than a blanket approval for the entire physical building.
