Alcohol (Ethanol), Serum

Alcohol (Ethanol), Serum

What it is

The Alcohol (Ethanol), Serum test measures the amount of ethanol (alcohol) present in the blood. It is commonly used to check for alcohol intoxication, monitor blood alcohol levels in medical or legal settings, and assess potential alcohol poisoning. This test provides a direct measurement of ethanol concentration in the bloodstream.

Uses

The test is used to confirm alcohol consumption, evaluate suspected alcohol intoxication, monitor patients in emergency or critical care situations, and provide evidence in legal or workplace-related cases. It is also helpful in detecting chronic alcohol misuse and guiding appropriate medical intervention.

Symptoms That May Lead to the Test

Doctors may order this test if a person shows signs such as confusion, slurred speech, unsteady movements, nausea, vomiting, impaired judgment, drowsiness, loss of consciousness, or suspected alcohol poisoning. It is also used when alcohol-related accidents or emergencies occur.

Abnormal Results

High Levels: Indicate alcohol intoxication, which may range from mild impairment to life-threatening alcohol poisoning depending on concentration. Chronic high levels may suggest alcohol dependence or abuse.

Low or Zero Levels: Suggest no recent alcohol consumption or complete elimination of ethanol from the body. Results must always be correlated with clinical symptoms and history.

Risks

This is a standard blood test with minimal risks. Possible side effects include mild pain, bruising, or bleeding at the puncture site, and rarely dizziness or infection.
