Methodology · worked example, guidelines & full notes
The four systemic markers (fever, tachycardia, anemia, elevated ESR) drive the severe classification when combined with frequent bloody stools.
When to use
Select daily stool count, rectal bleeding, and four systemic markers; the tool returns the severity category and the number of systemic features present.
How it works
Severe = ≥6 bloody stools/day plus ≥1 of (temp >37.8°C, HR >90 bpm, Hb <105 g/L, ESR >30 mm/h). Mild = <4 stools/day with no systemic features. Otherwise moderate.
Key points
- The four systemic markers (fever, tachycardia, anemia, elevated ESR) drive the severe classification when combined with frequent bloody stools.
- Meeting the severe criteria defines acute severe UC.

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.

| Blood in stool | Present |
| Temperature >37.8°C | Yes |
