Laboratory accreditation through the National Accreditation Board for Testing and Calibration of Laboratories (NABL) is a process that evaluates laboratories to ensure their testing and calibration systems meet quality standards. The process involves laboratories applying to NABL, undergoing a pre-assessment audit and final assessment, addressing any non-conformities, and receiving accreditation that is valid for two years if all standards are met. Accreditation through NABL improves testing reliability and gives laboratories greater credibility and business opportunities.
