When to use
Identify candidates for transfer to a thrombectomy-capable centre.
How it works
Facial palsy (0–1), arm weakness (0–2), speech (0–2), eye deviation (0–2), neglect (0–2); total 0–9. ≥ 4 suggests LVO.
Key points
- ≥ 4 suggests anterior LVO amenable to thrombectomy.
- Derived from NIHSS items predictive of LVO.
- Use alongside vascular imaging and transfer protocols.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Facial palsy | Absent (0) |
|---|---|
| Arm weakness | No drift (0) |
| Speech changes | Absent (0) |
| Eye deviation | Absent (0) |
| Denial/neglect | Absent (0) |
→FAST-ED0/9
- Interpretation：< 4 — lower likelihood of LVO.
| Facial palsy | Present (1) |
|---|---|
| Arm weakness | Falls/no effort (2) |
| Speech changes | Severe/global (2) |
| Eye deviation | Forced (2) |
| Denial/neglect | Two modalities (2) |
→FAST-ED9/9
- Interpretation：≥ 4 — likely large-vessel occlusion; consider thrombectomy-capable centre.

- Inputs: Facial palsy Absent (0), Arm weakness No drift (0), Speech changes Absent (0), Eye deviation Absent (0), Denial/neglect Absent (0) → Result: FAST-ED 0 /9（Interpretation: < 4 — lower likelihood of LVO.） Inputs: Facial palsy Present (1), Arm weakness Falls/no effort (2), Speech changes Severe/global (2), Eye deviation Forced (2), Denial/neglect Two modalities (2) → Result: FAST-ED 9 /9（Interpretation: ≥ 4 — likely large-vessel occlusion; consider thrombectomy-capable centre.）
