Ethanol concentration in serum or plasma (quantitative measurement)

Why This Test Matters

Alcohol is a common substance that can affect your health in many ways. This test helps doctors determine how much alcohol you’ve consumed recently or over time. It’s often used in medical emergencies, during alcohol detox, or to check for alcohol-related conditions like liver damage or addiction.

How the Test Works

Your blood or body fluid sample is tested using a specialized method to detect ethanol. The results show the concentration of alcohol in your system, measured in units like milligrams per deciliter (mg/dL). This helps healthcare providers make decisions about treatment or further testing.

Common Uses

Doctors may order this test if you’ve been exposed to alcohol in a dangerous way (e.g., poisoning), if you’re undergoing alcohol withdrawal, or if you have symptoms like confusion, slurred speech, or organ damage that could be linked to alcohol.

What to Expect Before the Test

You’ll typically have a small needle inserted into your arm or vein to draw blood. If testing urine or saliva, you may be asked to provide a sample in a sterile container. No special preparation is usually needed, but let your doctor know if you’re on certain medications or have a condition that might affect results.
