The average urine test can detect alcohol between 12 and 48 hours after drinking. More advanced testing can measure alcohol in the urine 80 hours after you drink. Breath tests for alcohol can detect alcohol within a shorter time frame. This is about 24 hours on average.

Yes, alcohol in a person’s breath does indicate the presence of alcohol in their blood, but the concentrations are different. When a person consumes alcohol, it enters the bloodstream and moves through the entire body. During the trip, it gets distributed in the lung tissues and with the air in one’s lungs.

Because alcohol metabolism is different for everyone, there is no single answer as to how long a breathalyzer can detect alcohol in a person’s system, but in general, a breathalyzer can first detect alcohol in a person’s system about 15 minutes after it has been consumed and up to 24 hours later.

Some breath analyzer software may automatically calculate blood alcohol values from the observed breath alcohol level. This process of equilibrium of alcohol between alveolar air and blood is based on Henry’s law, which states that the ratio between alcohol in blood and alcohol in deep lung air is constant.

Basically, two things determine how long a breathalyzer can detect alcohol. One is person’s blood alcohol concentration (BAC) level. The other is how long ago they drank. (“Breathalyzer” is really a brand name of an alcohol breath detector. Other names include Intoximeter, Draeger, Alcopro, BACtrack, Alcosensor, BAC Datamaster, and Intoxilyzer.) BAC declines at about .015 per hour. Thus, if the person’s peak BAC is a very high .15, it would be zero in ten hours. That is, dividing ...

Breathalyzers can detect alcohol within 15 minutes of your first drink and can continue for as long as the alcohol is in your system. Coffee, cold showers, and “sleeping it off” will not sober you up. Time is the only thing that can lower your BAC, so be smart about your drinking and always have a backup plan to get home.

The breathalyzer device is calibrated in such a manner to detect the infrared wavelength of alcohol—namely, the ethyl alcohol group—as this is what is used in alcoholic beverages. As you exhale into the device, the air passes through a chamber where the infrared beams look for and measure the wavelength of alcohol.

Breathalyzer tests ensure that pilots have not consumed alcohol in the last 12 hours and can fly safely. However, the nature of the tests (blowing into a device) has made it a concern during the pandemic. An Air India pilots union has asked the DGCA to suspend breathalyzer tests once again due to high cases.

While the SCRAM can be a helpful monitoring device, it does have some issues. First, it can overstate the alcohol concentration. About 1-5% of the alcohol consumed by a person is unmetabolized and exits the body unchanged. The SCRAM measures this alcohol sweated out through the skin.
