The ETOH medical abbreviation stands for ethanol, also called ethyl alcohol, which is the kind of alcohol found in beer, wine and liquor. In chart notes it is used as shorthand for alcohol and for a person's alcohol use.
The letters come from chemistry. Et is short for the ethyl group and OH is the hydroxyl group that makes the compound an alcohol, which is why chemists write it EtOH. Clinicians often type it in capitals as ETOH or EtOH. You may find it in a social history, an emergency department note, a lab result or a discharge summary. Below is how to read the common phrases, what an ETOH level means, and how the term is used respectfully in nursing and medical records.

What the ETOH medical abbreviation means in a note
When a clinician writes ETOH, they almost always mean drinking alcohol rather than rubbing alcohol or a lab chemical. It is a neutral, factual word. In a social history it describes how much and how often someone drinks. In an emergency note it may record that alcohol was involved in an injury or a change in alertness. In a lab report it names the test that measures alcohol in the blood.
The same letters can appear as a noun (ETOH use), as part of a test name (serum ETOH) or as part of a diagnosis phrase. The surrounding words show which use the writer had in mind.
Common ETOH phrases decoded
These phrases appear in real notes every day. The meanings below are the usual ones.
| Phrase in the chart | Usual meaning |
|---|---|
| Denies ETOH | The patient says they do not drink alcohol |
| Social ETOH | Occasional drinking, usually in social settings |
| ETOH 3 to 4 drinks/day | A record of the amount the patient reports |
| ETOH level 0 | No alcohol detected in the blood sample |
| Hx ETOH use disorder | A past or current diagnosis of alcohol use disorder |
| ETOH withdrawal | Symptoms that can follow stopping heavy, regular drinking |
An emergency department line: "Pt fell at home, smells of ETOH, ETOH level pending." The note records an odor of alcohol and a blood test that has been sent. It does not by itself say how much the person drank or what caused the fall.
Alcohol medical abbreviation on lab reports
A blood alcohol test may be listed as ETOH, serum ETOH, blood alcohol or ethanol level. Hospitals often report it in milligrams per deciliter, while legal blood alcohol limits for driving are usually given as a percentage, so the numbers on a hospital report and a police report can look very different even when they describe similar amounts.
Labs set their own reporting units and reference ranges, and a result is interpreted along with the person's symptoms and history. Breath tests and urine tests are other ways alcohol can be checked, each with its own uses.
Why clinicians ask about ETOH
Questions about drinking are routine, not a judgment. Alcohol can affect sleep, blood pressure, the liver, the stomach and mood, and it interacts with many medicines, including some pain relievers, sleep aids, seizure medicines and blood thinners. It also matters before surgery, because regular heavy drinking can affect anesthesia and recovery.
Some clinics use short screening questionnaires to ask about drinking in a consistent way. An honest answer helps the team give safer care. If you see something in your own chart that does not match what you said, you can ask to have it reviewed.
ETOH medical abbreviation in nursing care
In nursing notes, ETOH often appears next to a withdrawal plan. When a patient who drinks heavily every day is admitted, nurses may score symptoms such as shaking, sweating, anxiety and nausea on a scale like the CIWA protocol and report changes to the prescriber. Vital signs, sleep and orientation are watched closely, and an altered mental status is reported right away.
Nursing and coding students should know that a drinking history alone is not a diagnosis. A formal diagnosis such as alcohol use disorder is made by a clinician based on defined criteria. Find more shorthand used in daily charting in the chart notes and nursing guide.
Respectful language around alcohol use
Many health systems now prefer person-first wording, for example a patient who has alcohol use disorder, over labels that can feel blaming. ETOH itself is a neutral chemistry term, which is one reason it remains common. Writing the actual amount and pattern a patient reports is more useful to the next clinician than a vague word.
This is general information about what a chart term means. For questions about your own drinking, your medicines or a result in your record, talk with your doctor, nurse or pharmacist.
Frequently asked questions
What does ETOH stand for in medical terms?
ETOH stands for ethanol, also called ethyl alcohol. It is the alcohol in alcoholic drinks, and clinicians use it as shorthand for alcohol and alcohol use.
Why is alcohol abbreviated ETOH?
The term comes from chemistry. Et stands for the ethyl group and OH for the hydroxyl group, which together describe the ethanol molecule.
What does denies ETOH mean?
It means the patient told the clinician they do not drink alcohol. It records what the patient reported, not the result of a test.
Is ETOH a diagnosis?
No. ETOH names the substance. A diagnosis such as alcohol use disorder or alcohol withdrawal is written separately and is based on a clinician's assessment.
What is a normal ETOH level?
For a person who has not been drinking, the expected result is zero or below the lab's detection limit. Units and reporting rules differ between labs, so the result is read alongside the lab's own reference range.
