Background and Aims: Blood-based biomarkers have been proposed as an alternative to liver biopsy for non-invasive liver disease assessment (NILDA) in chronic liver disease (CLD). Our aims for this systematic review were to evaluate the diagnostic utility of selected blood-based tests either alone, or in combination, for identifying significant fibrosis (F2-4), advanced fibrosis (F3-4) and cirrhosis (F4), as compared to biopsy in CLD. Approach and Results: We included a comprehensive search of databases including Ovid MEDLINE(R), EMBASE, Cochrane Database, and Scopus through to April 2022. Two independent reviewers selected 286 studies with 103,162 patients. The most frequently identified studies included the simple aminotransferase-to-platelet ratio index (APRI) and fibrosis (FIB)-4 markers (with low-to-moderate risk of bias) in hepatitis B virus (HBV) and C virus (HCV), HIV-HCV/HBV co-infection, and nonalcoholic fatty liver disease (NAFLD). Positive (LR+) and negative (LR) likelihood ratios across direct and indirect biomarker tests for HCV and HBV for F2-4, F3-4, or F4 were 1.66-6.25 and 0.23-0.80, 1.89-5.24 and 0.12-0.64, and 1.32-7.15 and 0.15-0.86 respectively; LR+ and LR for NAFLD F2-4, F3-4 and F4 were 2-65-3.37 and 0.37-0.39, 2.25-6.76 and 0.07-0.87, and 3.90 and 0.15 respectively. Overall, proportional odds ratio indicated FIB-4 <1.45 was better than APRI <0.5 for F2-4. FIB-4 >3.25 was also better than APRI >1.5 for F3-4 and F4. There was limited data for combined tests. Conclusions: Blood-based biomarkers are associated with small-to-moderate change in pre-test probability for diagnosing F2-4, F3-4, and F4 in viral hepatitis, HIV-HCV co-infection, and NAFLD, with limited comparative or combination studies for other CLD.
