Hemostasis in Liver Cirrhosis and Hepatocellular Cancer

This study is looking at how blood clotting and bleeding processes work differently in people with advanced liver disease (cirrhosis) and liver cancer compared to healthy individuals. Cirrhosis changes how the liver makes clotting proteins, and researchers want to better understand these changes to improve care. Participants will have blood samples taken — no experimental treatment is given. **You may be eligible if...** - You are 18 or older - You have decompensated liver cirrhosis (advanced liver scarring with complications) - OR you are a healthy volunteer aged 18 or older willing to serve as a comparison **You may NOT be eligible if...** - You have had another type of cancer (outside the liver) in the past year - You have a blood clotting disorder not related to your liver disease - You have a blood disease such as leukemia, abnormal platelet counts, or hemoglobin disorders - You have had a previous liver transplant - You have received a blood transfusion in the last 7 days - You take blood thinners or antiplatelet medications (other than a preventive low-dose blood thinner) Talk to your doctor to see if this trial is right for you.
