Accreditation is a process whereby an independent assessment by a recognized third party affirms that a laboratory has technical competence to perform specified tests or calibrations.

Accredited Testing Laboratories




Marketing Tool
Accreditation is an effective marketing tool for testing and calibration laboratories as it is regarded as a reliable indicator of technical competence.  Accredited laboratories issue test or calibration reports bearing the accreditation body’s symbol as an indication of their accreditation.

Benchmark for performance
Many laboratories operate in isolation with their peers and are unable to comparatively assess their performance standards. Laboratory accreditation allows laboratories to determine their performance. During accreditation activities the accreditation body assesses all aspects of a laboratory’s facility and operations to ensure the production of accurate test data. Areas for improvement are identified and the laboratory is required to make the necessary corrective action to improve their performance quality.

International Recognition
Accreditation bodies conduct assessments against the requirements of International Standards.  This allows a uniform approach to determining a laboratory’s competence which in turn allows countries to mutually accept each other’s accredited test or calibration data through international agreements referred to as Mutual Recognition Arrangements (MRAs).  This system of MRAs between accreditation bodies has enabled laboratories to have the benefit of international recognition of their test or calibration data.



TTLABS accredits laboratories to the International standards:

ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories

ISO 15189: Medical Laboratories- Requirements for competence and quality

What do I need to become accredited?

Laboratories Interested in applying for accreditation would be required to be familiar with the relevant standard to which accreditation is being sought and must have a fully functional Quality Management System supported by policies, procedures and records. TTLABS also requires that the applicant laboratory be successfully participating in proficiency testing programmes approved by TTLABS and relevant to their desired scope of accreditation.
