Background. The subject of this article is the role of forensic toxicology in post-mortem examinations using immunofluorescence methods, its implications and its role in providing conclusive evidence for both criminal and civil proceedings. The aim of the study is to verify the correlation between the mode of death and the ingestion of exogenous substances and, if positive, to identify the category of substances ingested and assess their role in the cause of death. Materials and methods. A laboratory study was carried out, consisting of several phases: pre-analytical phase; analytical phase; post-analytical phase. The variables analyzed were sex, cause of death, age. Abused substances tested: amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, tricyclic antidepressants, delta-9-tetrahydrocannabinol (cannabis), alcohol. Conclusions. Retrospective analysis was performed on a total sample of 55 cases. The most relevant data emerged: cocaine with an incidence of 7.3% (4 cases out of 55), amphetamines with 5.4% (3 cases in total). The results of the screening tests were then subjected to confirmatory tests. There is an association between the use of certain exogenous substances and an increased risk of certain causes of death, such as overdose, traffic accidents, cardiovascular deaths, etc. This paper has highlighted the possibility of using first level immunological tests, such as immunofluorescence, to provide preliminary answers to the judicial authority immediately after autopsy, and a quantitative deepening with further second level tests, such as gas chromatography, as a gold standard to determine the cause of death.

Abstract

Background. The subject of this article is the role of forensic toxicology in post-mortem examinations using immunofluorescence methods, its implications and its role in providing conclusive evidence for both criminal and civil proceedings. The aim of the study is to verify the correlation between the mode of death and the ingestion of exogenous substances and, if positive, to identify the category of substances ingested and assess their role in the cause of death. Materials and methods. A laboratory study was carried out, consisting of several phases: pre-analytical phase; analytical phase; post-analytical phase. The variables analyzed were sex, cause of death, age. Abused substances tested: amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, tricyclic antidepressants, delta-9-tetrahydrocannabinol (cannabis), alcohol. Conclusions. Retrospective analysis was performed on a total sample of 55 cases. The most relevant data emerged: cocaine with an incidence of 7.3% (4 cases out of 55), amphetamines with 5.4% (3 cases in total). The results of the screening tests were then subjected to confirmatory tests. There is an association between the use of certain exogenous substances and an increased risk of certain causes of death, such as overdose, traffic accidents, cardiovascular deaths, etc. This paper has highlighted the possibility of using first level immunological tests, such as immunofluorescence, to provide preliminary answers to the judicial authority immediately after autopsy, and a quantitative deepening with further second level tests, such as gas chromatography, as a gold standard to determine the cause of death.
