Abstract |
The reliability and accuracy of blood alcohol concentration results presented in South African courts in respect of possible driving under the in uence (DUI) cases, have in recent years been subjected to intense scrutiny and severe criticism. Research has shown that multiple factors may negatively affect the reliability of results obtained from the analysis of such samples - including inappropriate or non- standardised sample management. In particular, long delays between sample acquisition and analysis may compromise the validity of results. Such delays may also negatively affect the outcome of both criminal and civil legal proceedings in possible DUI cases. A retrospective descriptive study was conducted on records from the Pretoria Forensic Chemistry Laboratory (PFCL) regarding the relevant dates pertaining to blood samples from deceased persons that were received for analysis. The parameters included the dates of sample acquisition at medico-legal mortuaries, delays in submission of samples to the laboratory, and dates of actual analyses. In addition, the expiration dates of sample collection kits were recorded. Our results show that numerous expired kits were utilised and that there was an average delay of approximately ve months between sample acquisition and laboratory analysis. This delay period varied greatly but appears to correlate with geographical distances of medico-legal mortuaries from the PFCL. In order to optimise and facilitate the administration of justice in both criminal and civil cases of alleged DUI, these shortcomings should be urgently addressed. Language: en |
