SteatoTest (ST) and NashTest (NT) would permit a simple and non-invasive semi-quantitative estimate of steatosis and NASH combining 13 parameters: age, sex, height, weight, triglycerides, cholesterol, alpha-2-macroglobulin, apolipoprotein A1, haptoglobin, gamma-glutamyltranspeptidase, transaminases ALT, AST and total bilirubin [56], but their reliability is not demonstrated. This evidence concerns the gene GPT and steatosis.
