Other fibrosis panels combining routine and proprietary tests include FibroMeterV2G (platelet count, prothrombin index, AST, alpha-2-macroglobulin, hyaluronic acid, urea, age, and sex) [75,76], FibroMeterV3G (using the same parameters as FibroMeterV2G, yet GGT instead of hyaluronic acid) [77], and FibroTest (alpha-2-macroglobulin, haptoglobin, GGT, age, bilirubin, apolipoprotein A1, and sex) [78]. Here, F2 is linked to fibrosis.
