NABL accreditation is a quality certification awarded to laboratories that meet international standards for testing and calibration. It is granted by the National Accreditation Board for Testing and Calibration Laboratories, an autonomous body operating under the Department of Science and Technology.
The purpose of NABL accreditation is to ensure that laboratories provide accurate, reliable, and internationally accepted test results.
During the accreditation process, laboratories are assessed on several parameters:
- Laboratory infrastructure and facilities
- Accuracy and calibration of testing equipment
- Competence of laboratory personnel
- Quality management systems
- Participation in proficiency testing programmes
Once accredited, a laboratory receives formal recognition of its technical competence and reliability.
Business loans can facilitate the process of obtaining NABL accreditation by providing financial support for the expenses involved in meeting the accreditation requirements. This may include investing in infrastructure upgrades, purchasing specialised equipment, hiring skilled personnel, and covering other associated costs. With the help of a business loan, laboratories and testing facilities can ensure they have the necessary resources to meet the stringent standards set by NABL, thereby enhancing their credibility and competitiveness in the market.

- Create a detailed standard operating procedure (SOP) for every laboratory investigation, ensuring proper environmental controls like temperature, humidity, and storage are maintained.
- Labs aiming for NABL accreditation must calibrate all instruments and equipment. Calibration must be performed exclusively by NABL-accredited calibration laboratories.
- Provide training to staff on documentation procedures, covering proper formatting, authorisation, issuance and withdrawal processes, as well as document review and change protocols. Each document should include an ID number, controlling authority's name, retention period, etc.
- It's important to remember that the quality manual serves as a policy document, which must be supported by additional procedural documents that also require proper preparation.
- Ensure that all processes outlined in the quality manual are thoroughly implemented.
- Document the internal quality control (IQC) measures used during patient testing, including uncertainties in measurements using tools such as Levy Jennings charts.
- Participate in External Quality Assessment Schemes (EQAS) and inter-laboratory comparisons for analytes not covered by available schemes.
- Record corrective actions taken in response to deviations in IQC/EQA results.
- Conduct internal audits and management reviews.
