MAFLD & Fibrosis Screening Calculator
Aggregates top validated lab-based scores with optimal ranges into one single screening tool.
(Not a diagnostic device.)
Outputs a single 0–5 steatosis likelihood and a fibrosis triage category. UI intentionally hides methods.

About this screening result
This result is generated from almost a dozen validated, laboratory-based steatosis and fibrosis indices. Your inputs are unit-normalized and checked for internal consistency. Each index is then converted into a probability-like signal using literature-anchored rule-out and rule-in zones with small sex-aware and lean-phenotype adjustments. Missing values are handled gracefully by re-normalizing the ensemble so that only available signals contribute.
About ranges & cutoffs
This tool uses operating ranges and optional cutoffs derived from peer-reviewed studies. They are screening-calibrated and are periodically updatable as new evidence accumulates. Specific thresholds, coefficients, and weights are intentionally not shown in the interface.
Intended use & next steps (triage, not diagnosis)
- 0–1: reinforce lifestyle guidance; re-assess if risk factors change.
- 2–3: consider nutritional therapy and/or non-invasive imaging based on clinical context.
- 4–5 or Fibrosis: High: refer for elastography or specialist evaluation per local pathways.
Results should be interpreted alongside history, exam, medications, and alternative liver disease etiologies.
