GPTC was established to support accredited laboratories in improving their testing capabilities, fulfilling accreditation requirements, and enhancing confidence among accreditation bodies, regulatory authorities, customers, and other stakeholders through inter-laboratory comparisons.
The Emirates International Accreditation Center (EIAC) granted accreditation to GPTC in February 2023, followed by PJLA accreditation in January 2024 for both its UAE and Pakistan branches. Within a year, GPTC has grown to become the region’s largest PT provider, with regular participants from across the GCC and several other countries worldwide.
GPTC offers accredited proficiency testing schemes in the following areas:
Proficiency Testing (PT) programs are structured assessments that evaluate the performance of laboratories by comparing their test results with those from other participants analyzing the same samples. These programs are designed to ensure that testing laboratories produce accurate and consistent results over time.
Through regular participation in PT programs, laboratories can objectively assess their testing processes and methods. The programs typically involve distributing identical samples to multiple laboratories, analyzing the results, and providing feedback to each participant. This process not only highlights variations in testing outcomes but also promotes transparency, standardization, and confidence in laboratory practices.
Proficiency testing is a key component of a quality management system and plays an essential role in maintaining technical integrity, especially in regulated environments. It fosters trust in the data generated by laboratories and contributes to the overall reliability of testing and measurement systems globally.
Proficiency Testing programs offer numerous advantages that contribute to the quality, credibility, and continuous improvement of laboratory operations:
