Classification

Ascites may be classified according to etiology into four groups:

• Portal hypertension
• Hypoalbuminemia
• Peritoneal disease
• Other diseases

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).
