In this MASLD Community Network talk, Lavinia Iordache, PA, walks through a real-world case to show how to accurately identify advanced liver fibrosis and, critically, how to distinguish F3 vs F4—a difference that drives management, eligibility for resmetirom (Rezdiffra), and surveillance strategy. She demonstrates a stepwise use of non-invasive tests (NITs)—FIB-4, FibroScan/VCTE with kPa and CAP, ELF serum biomarkers, and when to add MRE or biopsy—plus how to handle discordant/indeterminate results. The session covers cardiometabolic risk factors, lab patterns, and practical monitoring tips, including HCC surveillance considerations (modality choice in obesity, AFP/AFP-L3) and portal-hypertension cues that trigger EGD for varices. You’ll leave with a clear algorithm to stage disease, personalize treatment, and avoid missing F3 candidates who may otherwise be excluded by FIB-4 alone.
