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.
REQUIRED: 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.
