This test is a noninvasive assessment of liver status in patients with nonalcoholic fatty liver disease (NAFLD). Quantitative results of 10 biochemicals, in combination with age, gender, height, and weight, are analyzed using a computational algorithm to provide a quantitative surrogate marker (0.0-1.0) of liver fibrosis (Metavir F0-F4), hepatic steatosis (0.0-1.0, S0-S3), and nonalcoholic steatohepatitis (NASH) (0.0-0.75, N0-N2). The absence of steatosis (S < 0.38) precludes the diagnosis of NASH.
