Fatty Liver Disease, NAFLD, Nonalcoholic Fatty Liver Disease, Noninvasive Liver Biopsy, Steatohepatitis
Patient should be fasting for at least eight hours. Please indicate the patient's age, sex, height, and weight on the test request form. 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 comprised of 10 individual tests. For Medicare patients, 3 of these have Medicare coverage policies (cholesterol, triglycerides, and glucose). When ordering this test, consider Medicare's lipid and glucose coverage policies when entering reasons (ICD-9's) for this service.
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.
