3.2.1. Case no. 1
A 31-year-old female was found dead in her bedroom at home The victim was diabetic and insulin dependent. During the autopsy the pathologist collected peripheral blood, urine, vitreous humor and gastric contents for toxicological analysis of medical substances and alcohol. The blood sample did not reveal the presence of alcohol or medical substances, but a signal of acetone, methanol, acetaldehyde and 2-propanol was detected. Consequently, it was decided to confirm and quantify the VOCs by the HS GC-FID (Table 3 and Fig. 2). Volatile compounds such as acetone, methanol, 2-propanol and ethanol may be formed during physiological processes and can appear in a routine analysis in concentrations of up to 10 mg/L [30]. The amount of acetone found in the blood samples fitted the information of diabetes [1], and 2-propanol may be found in diabetes by acetone metabolism [31]. 2-propanol was found in a 2-propanol-to-acetone ratio
