What the engine reports

Priority

Marked aminotransferase elevation

LV-SAFE-02

Values this high are not typical of MASLD: acute hepatitis (viral, drug, ischemic, autoimmune) needs to be considered.

Detected clinical pattern

Pattern Meeting the 2023 MASLD Criteria

Steatosis with 1 cardiometabolic criterion/criteria and alcohol in range. Fibrosis risk by non-invasive tests: indeterminate.

  • Alcohol: Alcohol 3 g/day · MASLD range
  • Fibrosis risk: Fibrosis risk · indeterminate

Why this pattern was identified

  • MASLD criteria. Steatosis is documented and 1 cardiometabolic criterion/criteria are met (BMI 33).

Calculations

FIB-4
1.44

Lower cutoff 1.3; high above 2.67.

Recommended next steps

For physician consideration. Urgent review always comes first.

  1. 1Evaluate for acute hepatitis and other causes of marked aminotransferase elevation.
  2. 2Assess cardiovascular risk: it is the leading cause of death in MASLD.

LV-ALC-01Alcohol intake category

Inputs: alcohol 3 g/day (male)

Alcohol intake in the MASLD range.

LV-CALC-01Derived value

Inputs: age 38 · AST 150 · ALT 260 · platelets 245

FIB-4 = 1.44

LV-FIB-01FIB-4 and its stratum

Inputs: FIB-4 1.44 · cutoff 1.3

Indeterminate: second-line test needed.

LV-01MASLD criteria met

Inputs: steatosis documented · 1 cardiometabolic criterion/criteria: BMI 33 · alcohol in MASLD range

Pattern meeting the 2023 MASLD criteria.

LV-CV-01Cardiovascular risk assessment

Inputs: MASLD criteria met

Formal cardiovascular risk assessment is part of the work-up.

LV-04ALT above the AASLD upper limit

Inputs: ALT 260 U/L (limit 33 for male)

ALT above the sex-specific upper limit.

LV-SAFE-02Marked aminotransferase elevation

Inputs: peak aminotransferase 260 U/L

Values this high are not typical of MASLD.

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

  1. ✓ Low

    FIB-4 <1.3 (<2.0 from 65), stiffness <8 kPa

  2. ● Indeterminate

    Needs a second-line test

  3. ○ High

    FIB-4 >2.67, stiffness ≥12 kPa or ELF ≥9.8
