| Summary: | 碩士 === 國立臺灣大學 === 法醫學研究所 === 101 === According to the former reasearches, insufficient volume of blood sample and different types of collecting tubes may affect the analytical results of alcohol concentration. Our study showed that insufficient volume of blood sample leads to excess air space on the top of the tube where ethanol vapors and makes underestimation of blood alcohol concentration.
Sodium fluoride (NaF) collecting tubes can suppress glycolysis and ethanol formation is widely used for analysis of the blood alcohol concentration. In our study, comparison with NaF collecting tubes, blood alcohol concentration analysis using Ethylenediaminetetraacetic acid (EDTA) and Heparing tubes are more close to the expected value.
