Noninvasive markers of non–alcoholic fatty liver disease (NAFLD) used to asses fibrosis using the following equations.

Non-Invasive Markers of NAFLD
NFS	−1.67 + 0.037 x age + 0.094 BMI (kg/m2) + 1.13 x impaired glucose tolerance/DM (yes-1; no-0) + 0.99 AST/ALT ratio-0.013 x platelets (x109/L)- 0.66 x albumin(g/dL)
BARD	Sum of 3 variables (BMI ≥ 28—1 point; AAR ≥ 0.8—2 points; DM—1 point)
FIB-4	Age x AST(IU/L)
APRI	Platelet count(109) x √ALT(IU/L) AST/AST(Upper Limit of Normal (40 IU/L)) Platelet count(109)* 100

NAFLD fibrosis score (NFS), BARD score, Fibrosis-4 score (FIB-4) and AST to Platelet Ratio Index (APRI).
