Abstract: In the practice of forensic appraisal, accurate identification of body fluid stains and their tissue origin plays a key role in crime scene reconstruction and case solving. A systematic review of the advances in traceability technologies for common biological samples at the scene of a case is presented, including blood, saliva, semen, vaginal secretion, menstrual blood, etc. It focuses on the potential of recent research advances in precise traceability at the omics level, including transcriptomics (mRNA, circRNA, miRNA, and piRNA), epigenetics (tissue-specific DNA methylation profiles), microbiomics, and proteomics. This study further proposes that the synergistic development of the following areas represents the core direction for future development: introducing artificial intelligence algorithms, constructing a standardized testing system, integrating multi-omics data, and developing novel markers and on-site detection techniques. This integrated approach provides a systematic technical reference for the precise traceability of forensic body fluid stains.

Key words: forensic genetics, identification of body fluid stains, omics technique, accurate traceability
