ALCOHOL (ETHANOL), SERUM

Alcohol (Ethanol), Serum

What it is

The Alcohol (Ethanol), Serum test measures the amount of ethanol (alcohol) in the bloodstream. It is commonly used to assess recent alcohol consumption, detect alcohol intoxication, or monitor patients in clinical and legal settings. Ethanol is rapidly absorbed into the blood after drinking and affects the brain, liver, and other organs.

Uses

This test is used in emergency settings to diagnose alcohol poisoning, monitor individuals with suspected alcohol abuse, and support legal or workplace investigations. It is also helpful in assessing alcohol-related health conditions such as liver disease, pancreatitis, or altered mental status.

Symptoms That May Lead to the Test

Doctors may order this test if a person shows signs of alcohol intoxication, such as confusion, slurred speech, poor coordination, drowsiness, nausea, vomiting, difficulty breathing, or loss of consciousness. It may also be requested in cases of unexplained behavior changes or accidents.

Abnormal Results

High Ethanol Levels: Suggest alcohol intoxication, overdose, or chronic alcohol abuse. Very high levels can cause respiratory depression, coma, or death.

Low or Negative Ethanol Levels: Indicate no significant alcohol consumption, delayed testing after drinking, or complete sobriety.

Risks

The test involves a routine blood draw with minimal risks. Mild pain, bruising, or bleeding at the puncture site may occur, and rarely dizziness or infection can happen.
