A Biospecimen Proficiency Testing Program for Biobank Accreditation: Four Years of Experience.

Area of Science:

• Biotechnology
• Laboratory Science
• Quality Assurance

Background:

• Biobanks are crucial for producing and distributing quality-controlled biospecimens.
• Accreditation and certification are key steps in biobank professionalization.
• Proficiency Testing (PT) is a requirement for biobank accreditation.

Purpose of the Study:

• To introduce an international PT program for biobanks.
• To support biobank quality assurance and laboratory performance assessment.
• To provide insights into biospecimen testing and processing methods.

Main Methods:

• Development and provision of an international PT program.
• Inclusion of biospecimen testing schemes.
• Incorporation of biospecimen processing interlaboratory exercises.

Main Results:

• The PT program enables assessment of biobank laboratory performance.
• It offers insights into the performance characteristics of laboratory methods.
• Participation helps biobanks meet accreditation requirements.

Conclusions:

• International PT programs are essential for biobank quality assurance.
• These programs facilitate the validation of biospecimen qualification processes.
• The developed PT program supports biobank accreditation and standardization.
