These include the Hepatic Steatosis Index (HSI), the Liver Fat Score (LFS), the Fibrosis-4 (FIB-4), the Non-Alcoholic Fatty Liver Disease Fibrosis Score (NAFLD-FS) or the AST/Platelet Ratio Index (APRI), which are based on biochemical parameters obtained in routine blood analyses (AST, ALT, platelet count or albumin) and demographic and anthropometric parameters (age, sex or BMI) to estimate values that indicate the likelihood of NASH or liver fibrosis [4,6,8,9]. Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
