An additional 5 ml of whole blood and 5 ml of serum will be collected and stored by a research coordinator, nurse, research assistant, or investigator for analysis of specific biomarkers to include Hyaluronic acid, CK-18 (M30), FGF-21, Mac-2BP, FAS, AFP, YKL-40, Alpha-2-macroglobulin and a panel of 46 fatty acids during the liver biopsy appointment. Phlebotomies will be performed in Hepatology Research. The stored serum will be kept in the BAMC Gastroenterology Clinic in a -80 degree freezer and batch shipped to an outside lab periodically for analysis. Specimens will be identified by a designated research code only available to the local study team, thereby removing any personal identifiers on specimens prior to shipment to an outside lab.
