Blood collection, shipment, processing, and storage.

Area of Science:

• Biomedical research
• Cancer research
• Biospecimen science

Background:

• Whole blood and its fractions are vital biospecimens in population-based studies.
• Standardized procedures exist, but careful consideration is needed for new blood collection studies.

Purpose of the Study:

• To discuss critical issues in blood specimen collection, processing, storage, and dissemination for large-scale cancer research.
• To highlight factors influencing the use of blood as a source for DNA and various laboratory analyses.

Main Methods:

• Discussion of blood specimen handling within a workshop setting.
• Consideration of factors for collecting, processing, shipping, and storing blood and its components (serum, plasma, lymphocytes).
• Emphasis on quality assurance, standard operating procedures, and quality control.

Main Results:

• Blood specimens serve diverse research purposes, including DNA extraction and analyses on whole blood or fractions.
• Shipping conditions (ambient, cooled, frozen) and processing methods (fractionation, cryopreservation, nucleic acid purification) depend on intended use.
• Appropriate storage conditions are determined by intended analyses and storage duration.

Conclusions:

• Effective blood specimen management requires careful planning and adherence to strict quality assurance protocols.
• Standardized operating procedures and quality control are essential for reliable biorepository support in cancer research.
