Causes

Common Causes

Causes of high SAAG ("transudate") are:

• Cirrhosis - 81% (alcoholic in 65%, viral in 10%, cryptogenic in 6%)
• Heart failure - 3%
• Budd-Chiari syndrome or veno-occlusive disease
• Constrictive pericarditis

Causes of low SAAG ("exudate") are:

• Cancer (primary peritoneal carcinomatosis and metastasis) - 10%
• Tuberculosis - 2%
• Pancreatitis - 1%
• Serositis
• Nephrotic syndrome
