Breathalyzer Tests

There are various forms of breathalyzer tests that some officials may use as a preliminary test for drunk driving. These include fuel valve breathalyzers that measure your BAC through your exhaled breath and an electrochemical process.

There are also infrared breathalyzers that use special infrared technology to identify all of the ethanol molecules on your breath. Finally, there are semiconductor breathalyzers that use an electric current to measure your BAC. The greater the change in the electric semiconductor, the more alcohol is present in the body.

Urine Tests

Most law-enforcement officials do not use urine tests for DUIs. They go right to blood tests because they are more accurate. On the other hand, they are more accurate than breathalyzer tests, so they may be used in the interim between receiving ones of the breathalyzers listed above and getting a blood test. These tests simply measure the amount of alcohol in your urine.

Blood Tests

Finally, they are blood tests. These are the most accurate forms of blood-alcohol content tests available. They measure the amount of ethanol (alcohol) in your body at any given time via your blood.

Even though blood tests are regarded as the most accurate forms of blood alcohol content tests, these are sometimes wrong — and so are the other forms of tests. Breathalyzers are notably unreliable in many situations, and urine tests can be equally troublesome. Finally, blood tests can be contaminated with rubbing alcohol at the withdrawal site or be affected by other questionable factors.
