Patients with liver cirrhosis are at high risk of developing hepatocellular carcinoma (HCC) which implies significant mortality. At present current surveillance methods detect hepatocellular carcinomas at a late stage resulting in few treatment options for patients and, in the majority of cases, premature death. The goal of this study is to implement Elecsys® GAAD in real-world hepatocellular carcinoma surveillance for those with liver cirrhosis. The main questions it aims to answer are: * Does the introduction of the Elecsys® GAAD algorithm to the surveillance pathway increase early detection of HCC? * Does the introduction of the Elecsys® GAAD algorithm to the surveillance pathway reduce false positive tests and unnecessary confirmatory investigations? * Does the new surveillance pathway improve adherence? Researchers will compare Elecsys® GAAD with standard of care tests to see if it results in earlier detection of hepatocellular carcinoma and will explore potential improvements to the surveillance pathway.
