Overview
External Quality Assessment (EQA) Programs, also known as Proficiency Testing, are comprehensive evaluation services
organized by the Korean Association of External Quality Assessment Service (KEQAS).
These programs assess the accuracy and reliability of laboratory testing by comparing laboratory results according
to pre-established criteria, promoting standardization and quality improvement across participating laboratories.
Milestones
Operated since 1976, our EQA Programs represent Korea's premier quality assessment initiative for clinical laboratories.
We achieved a significant milestone by becoming the first in Korea to obtain ISO/IEC 17043:2010 international accreditation,
establishing a world-class proficiency testing system. As of 2025, we operate 95 programs covering 544 test items, and with
participation from over 2,000 institutions across medical facilities, hospitals, public health centers, and research institutes.
Vision
KEQAS is committed to continuously expanding our EQA Programs to advance laboratory medicine in Korea and
strengthen international competitiveness. Through our comprehensive external quality assessment services,
we foster excellence in laboratory practice and support improved laboratory practice for better patient outcomes.
