How long can alcohol be detected in breathalyzer

Breath: Alcohol can be detected in your breath via a breathalyzer test for up to 24 hours. Urine: Alcohol can be detected in urine for three to five days via ethyl gluconoride (EGT) metabolite or 10 to 12 hours via traditional method.

How long for alcohol to leave system for a breathalizer test?

Alcohol can be detected for a shorter time with some tests but can be visible for up to three months in others. The following is an estimated range of times, or detection windows, during which alcohol can be detected by various testing methods. Alcohol can be detected in your breath via a breathalyzer test for up to 24 hours.

How long after drinking alcohol can we detect it with a breath?

Any breath test during this 13 hour period would detect the presence of alcohol. However, after approximately 13 hours, when the alcohol was totally eliminated from the body, an alcohol test would give a negative result of .000. A person who has no alcohol in their system is not intoxicated, and a breath alcohol test of that person will give a negative result.

Alcohol breath-testing devices use the amount of alcohol in exhaled breath to calculate the amount of alcohol in a person’s blood, also known as blood alcohol concentration (BAC). Here’s how: When a person drinks alcohol, it goes into the stomach and small intestine and is quickly absorbed in the blood.
