🧫 BARD Score (NAFLD Fibrosis)
UseWhen to use: NAFLD/MASLD with BMI, AST/ALT, and diabetes status known.
Strata<2 high NPV for advanced fibrosis; ≥2 pursue FIB-4/elastography/biopsy pathway.
LimitsWhen not to use: already-cirrhotic staging pathways alone. · Pitfall: AST/ALT after alcohol binge. · Not a sole biopsy cancel.

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.
| BMI ≥28 kg/m² | No (0) |
|---|---|
| AST/ALT ratio ≥0.8 | No (0) |
| Type 2 diabetes mellitus | No (0) |
→BARD0/4
- Cue：0–1 — low likelihood of advanced fibrosis (high NPV in derivation)
| BMI ≥28 kg/m² | Yes (+1) |
|---|---|
| AST/ALT ratio ≥0.8 | Yes (+2) |
| Type 2 diabetes mellitus | Yes (+1) |
→BARD4/4
- Cue：2–4 — higher likelihood; pursue fibrosis staging (FIB-4/elastography/biopsy as indicated)

FAQ
Frequently asked questions
- Does BARD Score (NAFLD Fibrosis) 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 BARD Score (NAFLD Fibrosis) calculated in practice? Can you show a worked example?
- Inputs: BMI ≥28 kg/m² No (0), AST/ALT ratio ≥0.8 No (0), Type 2 diabetes mellitus No (0) → Result: BARD 0 /4（Cue: 0–1 — low likelihood of advanced fibrosis (high NPV in derivation)） Inputs: BMI ≥28 kg/m² Yes (+1), AST/ALT ratio ≥0.8 Yes (+2), Type 2 diabetes mellitus Yes (+1) → Result: BARD 4 /4（Cue: 2–4 — higher likelihood; pursue fibrosis staging (FIB-4/elastography/biopsy as indicated)）
