Q: How to differentiate between the Cardiac and hepatic (cirrhotic) source of Ascites?


Answer: Cardiac source of Ascites needs to fulfill 2 criteria

1. SAAG (Serum Ascites Albumin Gap) equal or more than 1.1 g/dL
2. Ascitic fluid Total Protein level equal or more than 2.5 g/dL

Cirrhosis from which cardiac source usually needs to be differentiated only satisfies first criteria.
