FibroTest is another validated marker for the quantitative assessment of fibrosis in NAFLD, ALD and chronic viral hepatitis.89 Combining five biochemical markers of haptoglobin, α2-macroglobulin, apolipoprotein A1, total bilirubin and GGT, corrected for age and gender, a mean standardised AUROC of 0.84 for advanced fibrosis in NAFLD patients was demonstrated using FibroTest in one meta-analyses. Here, APOA1 is linked to metabolic dysfunction-associated steatotic liver disease.
