Care must be taken during autopsy to remove blood from the heart, and not the pericardium, to provide a more accurate reflection of antemortem drug or alcohol levels. When an individual is suspected of driving under the influence, law enforcement agents can determine the extent of intoxication by measuring the blood alcohol concentration (BAC) and performing a standardized field sobriety test. Blood alcohol (ethanol) concentrations in decomposed bodies can mean drinking during life and/or endogenous production after death. Knowledge of basic pharmacological properties of alcohol and the inter- and intra-individual variations in alcohol absorption and elimination is essential for determining the role alcohol plays in modifying behavior and contributing to criminal behavior.

Your report may provide blood alcohol level test results in different ways depending on the laboratory that processes the test. Some investigators recommend measuring the water content of autopsy blood and if necessary correcting the concentration of ethanol to a mean value of 80% w/w, which corresponds to fresh whole blood. Serum methanol, ethylene glycol and isopropanol levels should also be obtained. Follow the institution's protocol Important!! Accessibility The unaccounted anions are formate in methanol and glycolate/glyoxylate/oxalate in ethylene glycol. (2) The person may have had a substance use disorder that resulted in consumption of high doses of the drug. Forensic toxicologists are often called upon to determine whether drug or alcohol intoxication was a contributing factor to a vehicle crash, workplace injury, or other fatal incident. Ethanol can be used as a therapeutic intervention in patients with methanol or ethylene glycol poisoning because of ethanol's much greater affinity for alcohol dehydrogenases.

The court however concluded that the alleged blackout did not prevent the defendant from starting the car by substituting a beer can opener for an ignition key, nor from driving the automobile in city traffic with normal ability, nor from fabricating a story in an attempt to protect himself from questioning by a police officer. This percentage would represent the maximum estimation of the BAC at the time of the accident. In addition, the odds ratio for being involved in a crash increases significantly at a BAC of 0.05 percent.57 Currently, all U.S. states specify a BAC of 0.08 percent as the cutoff for operating a motor vehicle under the influence of ethanol.58 Because of the rising concern about alcohol-related motor vehicle crashes involving people under the age of 21, all states have adopted zero-tolerance laws for underage drinking that make it a criminal offense if drivers under the age of 21 are found to have a BAC between 0.00 and 0.02 percent.59,60 While legislation has helped to establish BAC limits over the past 30 years, nearly 31 percent of all traffic-related deaths (10,076) in 2013 involved an alcohol-impaired driver with a BAC of 0.08 percent or more.61. True serum measurement as performed in most hospital laboratories using lactate dehydrogenase (more specific to lactate) will result in a true lactate.
