Clinical performance evaluation of the LIVERFAStTM Tests to determine fibrosis staging, inflammatory activity and steatosis grading compared with Liver Biopsy in patients with metabolic factors and presumed Non- Alcoholic Fatty Liver Disease (NAFLD).

The primary objective of this study is to assess the clinical performance of LIVERFAStTM In Vitro Diagnostic (IVD) Tests (Fibrosis score, Activity score and Steatosis score) in NAFLD suspected patients for staging of fibrosis and for grading of inflammatory activity and steatosis, taking as reference the liver biopsy with histological classification of the elementary lesions determined according to SAF scores
