NABL: INDIA’S NATIONAL ACCREDITATION BODY FOR TESTING AND CALIBRATION LABORATORIES

Context: The National Accreditation Board for Testing and Calibration Laboratories (NABL) has launched India’s first dedicated accreditation scheme for Mobile Food Testing Laboratories. The scheme aims to extend reliable and quality-assured food testing beyond conventional laboratories and closer to consumers, markets and remote communities.

Background: NABL functions as a constituent board of the Quality Council of India (QCI) and assesses the technical competence of conformity-assessment bodies. It accredits testing and calibration laboratories under ISO/IEC 17025 and medical laboratories under ISO 15189, besides other specialised bodies.

Salient Role: Accreditation means that a laboratory has been independently assessed for technical competence, impartiality, quality systems and reliability of results. This improves confidence among regulators, industry and consumers. NABL accreditation also supports wider international acceptance of Indian test reports and can reduce the need for repeated testing in overseas markets.

New Mobile Food Testing Scheme: The 2026 scheme creates a formal quality framework for mobile laboratories conducting food testing in the field. It is expected to strengthen food-safety surveillance, faster regulatory action, rural outreach and consumer confidence. This complements FSSAI’s wider testing network, including 305 Food Safety on Wheels units across 35 States/UTs and 259 NABL-accredited food-testing laboratories notified by FSSAI.

India’s Approach and Significance: India is increasingly using accreditation as part of its quality infrastructure, linking laboratory reliability with consumer protection, export competitiveness and Ease of Doing Business.

Current Status: The new accreditation scheme is operational and represents a shift from fixed laboratory testing towards quality-assured mobile testing, especially useful for food adulteration checks, surveillance and last-mile regulatory enforcement.

Analytical Questions

1. Question: Why is laboratory accreditation important if a laboratory already has qualified scientists and modern equipment?

Answer: Good equipment and qualified staff are important, but they do not automatically guarantee reliable results. Accreditation checks the entire testing process, including calibration, sample handling, quality control and impartiality. It creates an independent layer of trust. This is especially important when test reports affect public health, trade or regulatory action.

2. Question: What practical advantage can mobile food testing laboratories provide over fixed laboratories?

Answer: Mobile laboratories can reach markets, villages and remote areas where permanent testing facilities may not exist. They can provide quicker screening and support immediate enforcement against unsafe or adulterated food. However, they must follow the same quality standards as fixed laboratories. Speed should not come at the cost of accuracy.

3. Question: How can NABL accreditation improve India’s export competitiveness?

Answer: Exporters often face repeated testing when foreign buyers do not trust domestic reports. Internationally accepted accreditation can reduce such duplication. This saves time and cost and improves confidence in Indian products. But accreditation alone is not enough. Product quality, traceability and compliance with importing-country standards must also remain strong.

4. Question: Could greater use of mobile testing create risks of wrong enforcement decisions? How should this be handled?

Answer: Yes. Field conditions, equipment limits or poor sample handling can affect results. Mobile testing should therefore be backed by standard procedures, regular calibration and trained staff. Screening results should be confirmed by reference laboratories where necessary. Enforcement must be evidence-based so that genuine businesses are not unfairly penalised.

5. Question: If you were a District Magistrate, how would you use NABL-accredited mobile food laboratories effectively?

Answer: I would deploy them based on risk, not randomly. High-risk markets, festival seasons, school meals and repeated complaint areas should get priority. Results should be linked with FSSAI enforcement and public awareness. I would also track repeat violations and ensure confirmatory testing before serious penalties are imposed.
