Ascites Diagnosis
The differential diagnosis of ascites is often clarified by the calculation of the serum albumin to ascites gradient (SAAG).
SAAG = (serum albumin in g/dL) − (ascitic albumin in g/dL)
- High SAAG > 1.1 g/dL – Indicative of portal hypertension[1]
- Cirrhosis
- Heart failure
- Ascites total protein > 2.5 g/dL suggests cardiac ascites[2]
- Alcoholic hepatitis
- Budd-Chiari syndrome
- Portal vein thrombosis
- Low SAAG < 1.1 g/dL
- Malignancy / peritoneal carcinomatosis
- Nephrotic syndrome
- Pancreatitis
- Peritoneal tuberculosis
- Serositis
- Bowel infarction
- Chylous
