What the engine reports
Detected clinical pattern
Fibrosis Screening Opportunity
Steatosis is not documented, but the risk profile warrants FIB-4 under AASLD 2023. This is not a MASLD diagnosis. Fibrosis risk by non-invasive tests: low.
- Fibrosis risk: Fibrosis risk · low
Calculations
- FIB-4
- 1.17
Lower cutoff 1.3; high above 2.67.
Recommended next steps
For physician consideration. Urgent review always comes first.
- 1Review the FIB-4 result and consider liver imaging to document steatosis.AASLD 2023 recommends FIB-4 in these risk profiles.
Evidence and rule trace · 4 rules
LV-02Steatosis not documented, fibrosis screening indicated
Inputs: type 2 diabetes · steatosis not documented
Fibrosis screening opportunity.
LV-04ALT above the AASLD upper limit
Inputs: ALT 31 U/L (limit 25 for female)
ALT above the sex-specific upper limit.

Physician adjudication required. Clinical decision support for physician review. This output classifies steatotic liver disease under the 2023 nomenclature and stratifies fibrosis risk. It does not stage fibrosis by itself, diagnose a cause, or recommend a drug. Physician adjudication is required.

Fibrosis risk by non-invasive tests
● Low
FIB-4 <1.3 (<2.0 from 65), stiffness <8 kPa
○ Indeterminate
Needs a second-line test
○ High
FIB-4 >2.67, stiffness ≥12 kPa or ELF ≥9.8
