Differentiating Cirrhosis from other Diseases

Ascites may be caused by portal hypertension due to cirrhosis of liver or due to other causes like malignancies etc.,

Ascitic fluid analysis should be done to broadly categorize the cause of ascites.

Ascites is broadly classified as two types based on the Serum-ascites albumin gradient (SAAG):

• Transudate - SAAG > 1.1 g/dL (indicates the ascites is due to portal hypertension).
• Exudate - SAAG < 1.1 g/dL (indicates the ascites is due to non-portal hypertension etiology).
