| Viral Studies | Tests to determine if the recipient has viruses that may increase the likelihood of infecting the donor organ. These include hepatitis B virus, hepatitis C virus, cytomegalovirus (CMV) and Epstein-Barr virus (EBV). |
| Bilirbuin | Bile pigment which is made by the liver and is excreted in the bile. Elevated levels of bilirubin often indicate an obstruction of bile flow or a defect in the processing of bile by the liver. |
| Albumin | Protein made by the level. Below-normal levels are associated with many chronic liver disorders. |
| Clotting Studies | Tests that measure the time it takes for blood to clot are often used before liver transplantation. Blood clotting needs vitamin K and proteins made by the liver. Liver cell damage and bile obstruction can both interfere with proper blood clotting. |
| Liver Biopsy | A procedure in which tissue samples from the liver are removed (with a needle) from the body for examination under a microscope. |
| Creatinine | Compound formed in protein metabolism and present in much living tissue. |
| Anti-Rejection Medicines | Medicines which must be given for the rest of the individual's life to fight rejection of a transplanted organ. |
| Hepatobiliary Scintigraphy | An imaging technique of the liver, bile ducts, gallbladder, and upper part of the small intestine. Also called a HIDA scan. |
| Percutaneous Transhepatic Cholangiography (PTC) | A radiological technique used to visualize the anatomy of the biliary tract. A contrast medium is injected into a bile duct in the liver, after which X-rays are taken. |
| Autoimmune Hepatitis | redness or swelling (inflammation) of the liver. It happens when your body’s disease-fighting system (immune system) attacks your liver. |
| Acute Hepatic Necrosis | When tissue in the liver dies. Possible reasons include acute infections and reactions to medicine, drugs, or toxins. |
| Cirrhosis | Disease when healthy liver tissue is replaced with scar tissue. This stops the liver from working properly. Common cause of end-stage liver disease. |
| Fulminant Hepatic Failure | Severe impairment of hepatic functions or severe necrosis of hepatocytes in the absence of preexisting liver disease. |
| International Normalized Ratio (INR) | Diagnostic test used to measure clotting time. |
| Cholestasis | Any condition in which bile flow is slowed or stopped. |
| Jaundice | A yellow discoloration of the skin and eyes. This occurs when you have very high levels of bile pigment (bilirubin) in the blood |
| Hepatomegaly | Enlarged liver which is a condition that is often a sign of liver disease. |
| Portal hypertension | High blood pressure in the portal vein, the vein which sends blood to the liver from the intestine and spleen. |
| Esophageal Varices | Enlarged (dilated) veins in the lower part of the esophagus which are likely to bleed and can appear in people with severe liver disease. |
| Ascites | Fluid buildup in the belly (abdominal) cavity caused by fluid leads from the surface of the liver and intestine. |
| Liver Failure | Severe breakdown of liver function. Liver failure happens when a large part of the liver is damaged from any type of liver disorder. |
| Hepatic Encephalopathy | Harm to the brain and nervous system occurring because of toxic substances building up in the blood, toxins which are normally removed by the liver. |
