Example
- Triglycerides
- 150 mg/dL
- BMI
- 30 kg/m^2
- GGT
- 60 U/L
- Waist circumference
- 100 cm
Result: Fatty Liver Index 80.84: 60 or above -- hepatic steatosis is ruled in.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Thresholds
- below 30 rules steatosis out; 60 or above rules it in; 30-60 indeterminate.
What you enter
- Triglycerides
- BMI
- GGT
- Waist circumference
How this is calculated
- Formula
- y = 0.953 x ln(TG) + 0.139 x BMI + 0.718 x ln(GGT) + 0.053 x waist - 15.745; FLI = 100 x e^y / (1 + e^y), range 0-100.
