INS and Insulin resistance: Other laboratory biomarkers, such as aspartate-amino transferase (AST), the AST/ALT ratio (AAR), the AST/platelet ratio (APRI), gamma-glutamyl transferase (GGT), bilirubin, glucose, insulin, triglycerides, the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), alpha2-macroglobulin, apolipoprotein A1, haptoglobin, leptin, interleukin-6 (IL-6), tumor necrosis factor (TNF) α, and fibroblast growth factor-21 (FGF-21) were also shown to be correlated with the presence of MAFLD [2,81,82].
