Serum Ascites Albumin Gradient (SAAG) - Differential Diagnosis
High albumin gradient (>1.1 g/dl):
 - Cirrhosis	
 - Alcoholic hepatitis	
 - Cardiac ascites	
 - Massive liver metastases	
 - Fulminant hepatic failure	
 - Hepatic vein thrombosis (Budd-Chiari syndrome)	
 - Portal vein thrombosis	
 - Veno-occlusive disease	 
 - Acute fatty liver of pregnancy	 
 - Myxedema	 
 - "Mixed ascites"	 
Low albumin gradient (<1.1 g/dl):
 - Peritoneal carcinomatosis
 - Tuberculosis 
 - Biliary ascites without cirrhosis
 - Nephrotic syndrome
 - Ascites associated with connective tissue disease
 - Ascites associated with bowel ischemia/infarction
