how long can blood test detect alcohol
Alcohol is metabolized at the rate of .015 of (BAC) every hour. For example, an individual with a BAC of .15 (almost twice the legal limit for driving in all 50 states) will have no measurable alcohol in his or her blood 10 hours after consuming the last drink (.15 divided by .015 = 10).o, the EtG Urine Alcohol Test cannot show how much alcohol a person ingested, but it can, by way of comparison, detect alcohol consumption after the alcohol has been metabolized by the body.
