A Novel Fibroblast Activation Protein‐Based Algorithm to Assess Fibrosis in Metabolic Dysfunction–Associated Steatotic Liver Disease

Without a need for elastography, applying FAP Index following FIB-4 or NFS can facilitate accurate risk stratification of patients by greatly reducing the frequency of indeterminate results compared to FIB-4 or NFS alone, without compromising negative predictive value. Thus, FAP Index is a novel, fibrogenesis-relevant, rapid, robust diagnostic tool suited to increasing the efficiency of liver fibrosis triage in primary care.
