LCN2 and Cirrhosis: Diagnostic biomarkers such as natriuretic peptides, troponins, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), along with emerging imaging techniques like artificial intelligence-cirrhosis-electrocardiogram (ACE), echocardiography, and point-of-care ultrasound (poCUS) are reviewed.
