Classic 4-item screening test for alcohol problems. CAGE is part of standard practice in this setting because it provides a structured, replicable assessment that can be tracked over time and compared across patients or visits.
Like all screening or assessment instruments, CAGE is a structured aid — not a diagnostic test in isolation. Results should be interpreted alongside history, examination, and clinical context. Where a score crosses an actionable threshold, the next step is typically a more detailed clinical evaluation rather than a definitive diagnosis.
Answer all 4 items below to see your CAGE score and interpretation.
All scoring runs in your browser. No data is sent anywhere — close the tab and the answers are gone.
Score 1 point per yes answer. Total range 0-4. Score >= 2 suggests alcohol problems.
Scoring notes: Score 1 point per yes answer. Total range 0-4. Score >= 2 suggests alcohol problems.
The cutoffs below are drawn from the published validation literature. Always interpret in clinical context.
| Score range | Band | Interpretation |
|---|---|---|
| 0–1 | Low risk | None |
| 2–4 | Possible alcohol problem | Further evaluation |
This is an illustrative walkthrough, not a real patient. Follow the same four steps with your own answers — or use the live calculator at the top of this page.
Mark each item Yes or No. Each "Yes" adds the item's weight; each "No" adds 0. The example below uses illustrative answers.
| # | Item | Example response | Score |
|---|---|---|---|
| 1 | Have you ever felt you should Cut down on your drinking? | Yes | 1 |
| 2 | Have people Annoyed you by criticizing your drinking? | Yes | 1 |
| 3 | Have you ever felt bad or Guilty about your drinking? | Yes | 1 |
| 4 | Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover (Eye-opener)? | No | 0 |
Add the weights from the items where you marked "Yes" (skip the "No" answers — they contribute 0).
1 + 1 + 1 + 0 = 3
Find the row in the interpretation table whose range contains your total:
Total = 3 falls between 2 and 4 → Possible alcohol problem
Possible alcohol problem. Further evaluation
