Ethanol Neogenesis in Stored Blood
Journal Title: Peer Reviewed Journal of Forensic & Genetic Sciences - Year 2018, Vol 1, Issue 3
Abstract
During the investigation of accidental cases, blood samples obtained from accidental victim are submitted to forensic science laboratory for toxicological analysis. All through, ethanol analysis is performed on almost all cases of blood samples. The main problem is determining alcohol concentration in these cases is changes in Blood Alcohol Concentration (BAC) that can occur due to neo formation of ethanol. Blood samples stored under in sufficient conditions or for longer times and body fluids have undergone petrifaction often contains certain amount of volatile compounds. In the light of possibility that, neo formation of ethanol in improperly stored blood might give rise to an incorrect estimation of BAC. With this in mind, to study the effect of preservative and temperature on the formation and concentration of ethanol in blood samples, we estimated the ethanol neo genesis in stored and normal blood in different time period (0, 7, 14, 21, 28, 35 and 42 days). Head Space-Gas Chromatography instrument used to measure the level of ethanol in blood sample. We found that neo formation of ethanol was observed in normal blood sample. There was no any neo formation observed in blood sample with preservative and blood stored at 4 °C. Our study is supporting the studies which suggest that storage condition will affect the neo formation of ethanol in blood samples.
