TG18 I–III.
When to use
When to use: after TG18 diagnostic criteria suggest acute cholangitis.
How it works
III if organ dysfunction; else II if ≥2 moderate factors; else I.
Key points
- TG18 I–III.
- OD ⇒ III.
- Next: abx ± drainage.

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.
| Suspected/definite acute cholangitis (TG18 diagnostic criteria met) | Yes — grade severity |
|---|---|
| Any organ dysfunction (CV / neuro / resp / renal / hepatic / heme — TG18 Grade III defs) | Yes → Grade III |
| WBC >12 or <4 ×10⁹/L | Yes |
| Fever ≥39°C | Yes |
| Age ≥75 y | Yes |
| Total bilirubin ≥5 mg/dL | Yes |
| Hypoalbuminemia (below local LLN) | Yes |

- Cue：Grade III — organ dysfunction; urgent biliary drainage + abx

Frequently asked questions
- Does TG18 Acute Cholangitis Severity upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is TG18 Acute Cholangitis Severity calculated in practice? Can you show a worked example?
- Inputs: Suspected/definite acute cholangitis (TG18 diagnostic criteria met) Yes — grade severity, Any organ dysfunction (CV / neuro / resp / renal / hepatic / heme — TG18 Grade III defs) Yes → Grade III, WBC >12 or <4 ×10⁹/L Yes, Fever ≥39°C Yes, Age ≥75 y Yes, Total bilirubin ≥5 mg/dL Yes, Hypoalbuminemia (below local LLN) Yes → Result: TG18 grade III severe（Cue: Grade III — organ dysfunction; urgent biliary drainage + abx）
