What NABL does

NABL (National Accreditation Board for Testing and Calibration Laboratories) is India's national accreditation body, operating as an autonomous constituent board of the Quality Council of India (QCI), a government-affiliated quality assurance body. It provides third-party accreditation services to conformity assessment bodies including testing laboratories (ISO/IEC 17025), calibration laboratories (ISO/IEC 17025), medical laboratories (ISO 15189), proficiency testing providers (ISO/IEC 17043), reference material producers (ISO 17034), and biobanks (ISO 20387). NABL's accreditation is internationally recognized through signatory status to the ILAC and APAC Mutual Recognition Arrangements, enabling global acceptance of accredited test and calibration results.

NABL's product portfolio extends beyond core accreditation to specialized programs including the Government Drinking Water Testing Laboratory Accreditation Program (G-LAP), the Medical (Entry Level) Testing Labs (M(EL)T) program, Product Based Accreditation, Temporary Site Laboratories Testing, Soil Testing Laboratory Program, and an Integrated Assessment Scheme. The organization distributes its services through a centralized web portal (nablwp.qci.org.in) for applications and a public laboratory search tool, supported by four regional offices in New Delhi (headquarters), Bengaluru (South), Kolkata (East), and Ahmedabad (West). NABL also runs an Assessor Training Course to develop qualified assessors for evaluating conformity assessment bodies.

NABL generates revenue through accreditation fees structured by category, including application fees, assessment fees, and annual surveillance fees, with a 4-year accreditation cycle and annual on-site surveillance. The pricing model is best characterized as professional services with per-category and per-discipline fee tiers. As a government-affiliated autonomous body under QCI, NABL operates on a fee-for-service model and is not venture-capital funded or publicly traded. It maintains regulatory oversight through published lists of suspended, withdrawn, and adverse-action laboratories, enforcing quality standards across the accredited ecosystem.
