Chain of Custody in Forensic Toxicology

Chain of custody (COC) is a fundamental legal and procedural requirement in forensic toxicology that documents the complete handling history of evidence from collection through analysis to courtroom presentation. For Zambian university and college students pursuing diplomas or degrees in forensic science or biomedical sciences, mastering COC protocols is essential for ensuring evidence integrity and admissibility. This topic covers the meticulous documentation of who handled the evidence, when, where, and why, preventing tampering, loss, or contamination. Understanding COC is critical for careers in law enforcement, medical examination, and forensic laboratories across Zambia, where adherence to international standards like ISO 17025 is increasingly important. Learners will explore electronic tracking systems, legal accountability, and the consequences of COC breaches, equipping them with the skills needed for credible forensic practice and successful performance in professional examinations.
