DOI No. :

Research study was carried out to know whether alcohol is generated or lost in antemortem blood samples stored at different periods of time (2nd, 7th, 14th, 30th and 60th day) and with the presence or absence of preservative and refrigeration in antemortem blood samples of drunkenness patients brought to emergency medical department.Highlight of study is BAC (blood alcohol concentration) in samples without preservative and without refrigeration has fallen significantly as storage period increases at each point of time compared to BAC with preservative NaF (Sodium Fluoride) and with refrigeration at4°C. NaF and refrigeration of samples at 4oC significantly prevents loss of BAC in stored samples.BAC raised at 14th day in both the groups i.e. samples with preservative NaF and with refrigeration at 4°C & and samples without preservative and without refrigeration could be attributed to the microbial fermentation due to contamination. Kew Words: Blood Alcohol Concentration; Sodium Fluoride; Refrigeration.
