Applies the 2023 steatotic liver disease nomenclature.

Example
- Hepatic steatosis present
- Yes
- Body mass index
- 31
- Sex
- Female (HDL cut 50)
Result: MASLD
The tool opens with these values already filled in. Replace them with your own.
What the result means
- MASLD
- Hepatic steatosis with at least one of five cardiometabolic criteria, and alcohol below the MetALD band.
- MetALD
- The same, with an alcohol intake of 140 to 350 g/week in females or 210 to 420 in males. A category created in 2023.
- ALD
- Alcohol above the MetALD band.
- Cryptogenic SLD
- Steatosis with no cardiometabolic criterion and no other identified cause.
- Positive, not exclusion
- The old term required ruling out significant alcohol first. This one does not, and drinking above the threshold does not remove the diagnosis - it renames the category.
- The five criteria
- Adiposity by BMI or waist; dysglycemia or type 2 diabetes; blood pressure 130/85 or its treatment; triglycerides 150 or more; low HDL. Any ONE suffices.
- BMI is ancestry-specific
- The cut is 25 generally and 23 in those of Asian ancestry. Waist cuts vary by ancestry AND sex, with the Japanese thresholds inverting the usual sex ordering.
- HDL is sex-specific
- At or below 40 mg/dL in males, 50 in females. One figure for both misclassifies a predictable group.
- Alcohol is per WEEK
- The published bands are grams per week. The daily figures in circulation are approximations of them.
