Abstract

              This study was intended to compare levels of ethyl alcohol concentration in the blood and the vitreous humor of the deceased’s by using Headspace Gas Chromatography. Data were collected from 100 corps that submitted to the Forensic Chemical Section, Central Institute of Forensic Science in 2016 from which the level of alcohol concentration was examined. The samples of blood and vitreous humor from each corps were taken and analyzed by the forensic scientist within 72 hours.


               The resultant findings revealed a positive correlation between the alcohol concentration levels in blood samples and vitreous humor samples with the correlation coefficient (r) of 0.988 and at the statistical significance of 0.01, whereas the t-test analysis showed no statistical difference in those samples (t=0.188, p=0.851). Such correlation could be applicable to use the vitreous humor for alcohol concentration examination in case the blood samples were found to be degraded or unable to examine
