Special Instructions
The patient's age, gender, height, and weight at the time of collection must be submitted for FibroSure® testing.
Expected Turnaround Time
3 - 6 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Test Details
Use
This test is intended for noninvasive assessment of liver status in patients with alcoholic liver disease. 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 alcoholic steatohepatitis (ASH) (0.0-1.0, H0-H3).
Limitations
ASH FibroSure® is recommended for patients with suspected alcoholic liver disease. It is not recommended for patients with other liver diseases. It is also not recommended in patients with Gilbert disease, acute hemolysis, acute hepatitis, acute inflammation of the liver, extrahepatic cholestasis, transplant patients, and/or renal insufficiency patients. Any of these clinical situations may lead to inaccurate quantitative predictions of fibrosis.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA). The FDA has determined that such clearance or approval is not necessary.
