Serum-ascites albumin gradient >1.1g/dL is seen in 
Select and explain. 
A. Alcoholic cirrhosis, B. Tuberculosis, C. Pancreatitis, D. Malignant ascites
A: Alcoholic cirrhosis
Answer: A: Alcoholic cirrhosis 
Explanation: Serum ascites-to-albumin gradient (SAAG) When the gradient between the serum albumin level and the ascitic fluid albumin level is >1.1 g/dL, (ie; low protein in ascitic fluid compared to serum) the cause of the ascites is most likely due to poal hypeension; this is usually in the setting of cirrhosis. In patients with cirrhosis, the protein concentration of the ascitic fluid is quite low, with the majority of patients having an ascitic fluid protein concentration <1 g/dL.When the gradient is <1.1 g/dL, infectious or malignant causes of ascites should be considered.Ref: Harrison 19e pg: 2065
