Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [1] BAC is expressed as mass of alcohol per volume of blood. In US and many international publications, BAC levels are written as a percentage such as 0.08%, i.e. there is 0.8 ...
CDT is measured by taking a sample of a patient's blood. Apparently healthy individuals with no or low reported alcohol consumption and a negative Alcohol Use Disorders Identification Test (AUDIT) will have a %CDT <1.7% (95th percentile for the social drinking population). Elevated levels of CDT suggest recent heavy alcohol consumption ...
[5] [6] An increase of alcohol intake by ~20 g ethanol/day will raise the PEth 16:0/18:1 concentration by ~0.10 μmol/L, and vice versa if the alcohol consumption has decreased. However, it has been demonstrated that there can be significant inter-personal variation, leading to potential misclassification between moderate and heavy drinkers. [ 7 ]

Some effects of alcohol intoxication, such as euphoria and lowered social inhibition, are central to alcohol's desirability. [21] As drinking increases, people become sleepy or fall into a stupor. At very high blood alcohol concentrations, for example above 0.3%, the respiratory system becomes depressed and the person may stop breathing. [22]
