Blood, urine and other body fluids are analyzed to detect and quantify any alcohol or other volatile substances present. Interpretative evidence is given pertaining to blood alcohol concentrations and the operation of breath-testing equipment. Liquor, mash and illicit spirits are analyzed.

Services provided by the Alcohol Analysis Section of a forensic science laboratory include :

scientific support to the breath and blood alcohol testing programs of Police agencies; training police officers as Breathalyzer Technicians and assisting in the training of police officers as operators and calibrators of approved screening devices; analyzing body fluids, mainly blood samples, for alcohol and other volatile substances; giving expert testimony to the courts on the pharmacology of alcohol and on the theory and mode of operation of breath testing instruments.

Death from drinking alcohol (Ethanol) can either be from an acute short-term ingestion (accidental death) or from chronic, long term drinking (natural disease). The short-term ingestion that can cause death is a blood alcohol of 0.45 (20-25 drinks for a 150 lb. male). The long-term ingestion that can cause death varies with the weight, rate of consumption, physical activity and many other factors.

Alcohol is a poison that is metabolized at a rate of 2/3 of a drink per hour. This is called detoxification and the liver does it. The blood alcohol concentration is measured in milligrams of ethanol in 100 ml of blood or mg%. The legal limit in Canada is 80 mg% for operating a motor vehicle.

Two types of testing equipment used to determine the BAL (Blood Alcohol Level) are the Fuel Cell and the Chemical type equipment. The fuel cell type examples are the Alcotest, Alcosensor and the Intoxilyzer. An example of the chemical type is the Breathalyser which has been in use from the late 1960’s!
