What this tool is based on
This versioned record keeps the citations, equation or decision rule, units, test coverage, intended population, and exclusions attached to the tool.
How evidence review works →Patients requiring a structured assessment of conscious level using defined eye, verbal, and motor responses.
Best eye response (1–4) + verbal response (1–5) + motor response (1–6); total range 3–15 with component notation retained.
Categorical component scores only; no unit conversions.
Every eye, verbal, and motor response; 3–15 bounds; severe/moderate/mild ranges; and incomplete state.

Limitations and exclusions
- Do not report only the total when components are clinically relevant.
- Document untestable components and confounders such as intubation, sedation, paralysis, language barriers, intoxication, and pre-existing deficits.
- The total does not diagnose the cause or exclude important neurologic injury.
- Use an age-appropriate assessment in children who cannot be evaluated with adult verbal criteria.

About this tool
Glasgow Coma Scale (GCS) Calculator
Use this GCS calculator to document the best observed eye, verbal, and motor responses and view the 3–15 total without losing the components.
Untestable components and confounders must be documented. The total does not identify the cause of altered consciousness or exclude neurologic injury.
