Reagentcontrole

Reagentcontrole, or reagent control, is the systematic management and verification of chemical and biological reagents used in laboratory work. It encompasses procurement, storage, labeling, identity and quality verification, lot tracking, and documentation to ensure that reagents meet defined specifications and are suitable for their intended use. In regulated environments such as clinical and pharmaceutical laboratories, reagentcontrole forms part of formal quality systems that support traceability, reproducibility, and compliance with applicable standards.

Key components include supplier qualification and certificates of analysis, material safety data sheets, clearly labeled reagents with accurate expiry dates, and defined storage conditions. Positive identification by lot number and certificate, periodic re-testing or qualification for critical reagents, and robust inventory controls are essential. Modern implementations often rely on barcoding or RFID, integrated with laboratory information management systems (LIMS) or enterprise resource planning (ERP) software to track usage, shelf-life, and disposition.

Typical workflows involve receiving and inspection, accessioning into inventory, labeling with metadata (lot, expiry, storage), first-expire-first-out rotation, ongoing quality checks, and proper disposal of expired or compromised reagents. In practice, reagentcontrole contributes to data integrity and experimental reliability, while reducing waste and safety risks.

Standards and guidelines relevant to reagentcontrole include GLP and GMP practices in regulated settings, ISO 17025 for laboratory competence, and Good Distribution Practices (GDP) for reagents in the supply chain. Challenges include maintaining complete traceability, managing shelf-life, and preventing cross-contamination.
