An Ethyl Alcohol (EtOH) test is a test that measures the amount of alcohol in a person’s blood, urine, breath, or saliva.

Pre-test preparation: There is no specific preparation required for an EtOH test.

Testing method:

Blood test: A sample of blood is taken from a vein in the arm and sent to a laboratory for analysis.
Urine test: A sample of urine is collected and sent to a laboratory for analysis.
Breath test: A person blows into a breathalyzer machine, which measures the amount of alcohol in the breath.
Saliva test: A sample of saliva is collected and sent to a laboratory for analysis.

Common symptoms that may prompt your doctor to order an EtOH test include: slurred speech, unsteady gait, confusion, and impaired judgment.

Diagnosis: The results of an EtOH test are used to determine a person’s blood alcohol concentration (BAC) and to diagnose alcohol abuse or dependence.

Reference range:

Blood: 0.02% – 0.08%
Urine: 0.02% – 0.08%
Breath: 0.02% – 0.08%
