This article outlines the standardized packaging workflow for DNA database samples, ensuring sample integrity, traceability, and compliance with database storage requirements.
Core Packaging Workflow
-
Pre-Packaging Prep: Verify sample labeling (unique database ID, donor info, collection date); don sterile gloves and use lint-free wipes to clean work surfaces.
-
Primary Packaging: Place each sample (e.g., swab, blood card) into a sterile, tamper-evident microcentrifuge tube or sealed pouch; add desiccant if storing dry samples.
-
Secondary Packaging: Group primary packages into labeled storage boxes with dividers; mark boxes with batch ID, storage conditions (e.g., -20°C), and expiration dates.
-
Documentation & Tracking: Log package details (box ID, sample IDs, storage location) into the database’s LIMS; attach a physical label matching digital records.
-
Final Storage Prep: Seal boxes with tamper-proof tape; transport to designated storage units (freezers/archives) following temperature control protocols.
Key Workflow Requirements
-
Traceability: Every package links to a unique database ID for full sample lifecycle tracking.
-
Contamination Control: Sterile, single-use packaging and PPE prevent cross-sample interference.
-
Compliance: Aligns with database standards (e.g., CODIS, UK National DNA Database) for packaging and storage.
-
Durability: Primary/secondary packaging resists temperature fluctuations and physical damage.
Application Scope
-
Forensic DNA Databases: Packaging offender, victim, or crime scene samples for long-term storage.
-
Biobank Databases: Preparing genetic research samples for centralized database storage.
-
Clinical DNA Repositories: Packaging patient samples for disease-related DNA database inclusion.
