3. Classification of jaundice

4. Hx & P/E Information :  Use of drugs or herbal medications  Use of alcohol  Hepatitis risk factors  Abdominal operations, including gallbladder surgery  Inherited disorders including liver diseases and hemolytic disorders  HIV status  Travel history  Exposure to toxic substances Fever with chills, RUQ pain : acute cholangitis Anorexia, malaise, and myalgias : viral hepatitis Chronic liver failure/portal hypertension : Ascites, splenomegaly, spider angiomata, and gynecomastia Specific P/E finding Hyperpigmentation : hemochromatosis Kayser-Fleischer ring : Wilson's disease Xanthomas : primary biliary cirrhosis.

5. Lab studies Normal liver enzymes : – Hemolysis – Inherited disorders of bilirubin metabolism Indirect - Gilbert's and Crigler-Najjar syndrome Direct - Rotor and Dubin-Johnson syndrome ALP, AST/ALT : – Biliary obstruction – Intrahepatic cholestasis – Liver disease – AST/ALT ratio Serum total and indirect bilirubin Alkaline phosphatase Aminotransferases Prothrombin time Albumin

6. Subsequent Studies Evaluatation another disease; confirm Liver Bx Imaging tests : – Abdominal U/S – Endoscopic U/S – Abdomen CT, MRI – ERCP, PTC Serologic tests - viral hepatitis Antimitochondrial antibodies - primary biliary cirrhosis Antinuclear anti-sm, LKM antibodies - autoimmune hepatitis Serum levels of iron, transferrin, ferritin - hemochromatosis Serum levels of ceruloplasmin - Wilson's disease a-1 antitrypsin activity - a-1 antitrypsin deficiency
