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 ...

Binge drinking is defined as the amount of alcohol it takes to raise a person’s blood-alcohol concentration level to 0.08, the legal definition of being intoxicated in most states.

[134] Measurement of ethanol levels in the blood, urine and breath are also used to assess recent alcohol intake, often in the emergency setting.
But 72% of drivers tested had BAC over 0.08%. Calculating sensitivity (98.1%) and specificity (71.1%), which are independent of prevalence, if these are held constant but only 1% of drivers tested had BAC over 0.08%, the arrest accuracy using SFSTs would fall to 3.3% (due to a large number of false arrests) and the overall accuracy to 71.3%.
