Fatty Liver Disease, NAFLD, Nonalcoholic Fatty Liver Disease, Noninvasive Liver Biopsy, Steatohepatitis
This test is a noninvasive assessment of liver status in patients with nonalcoholic fatty liver disease (NAFLD).
Patient should be fasting for at least eight hours.
The patient's age, gender, height, and weight at the time of collection must be submitted.
Separate serum from cells within two hours of collection. Specimen can be stored refrigerated at 2°C to 8°C for 72 hours and frozen at -70°C for seven days. Frozen samples are stable for one freeze/thaw cycle.
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.
