GCCL participated in the 2024 Biorepository Proficiency Testing Program – Viable PBMC Isolation,
organized by the Integrated Biobank of Luxembourg (IBBL), a global standard-setting organization for biospecimens.

Based on the evaluation results, GCCL was granted a certificate of participation, meeting all required standards.  

This internationally recognized proficiency testing program adheres to the standards of the International Society for Biological and Environmental Repositories.
It assesses the accuracy and reproducibility of PBMC (Peripheral Blood Mononuclear Cell) isolation, as well as the quality control of biological samples.

The evaluation was conducted by the ISBER Proficiency Testing Advisory Group, comprising experts from various countries.
The official results were released in March 2025.

The certification awarded to GCCL includes the official recognition that all evaluation criteria were successfully met, along with our participant number (L630).

This participation allowed GCCL to confirm its technical capability and quality system in alignment with international standards.

GCCL has a team with experience in PBMC processing and continues to build expertise through active engagement in the field.

With the introduction of a computerized system to support secure and reliable specimen management, 

we are continuously working to enhance service quality.

Moving forward, GCCL will continue to validate its quality management system through regular international certifications,
and strive to grow as a clinical trial sample analysis organization that aligns with and contributes to advancing global standards.
