Serum Ascites to Albumin Gradient (SAAG)

Determine if ascites due to portal hypertension.

About

The serum to ascites albumin gradient (SAAG) can be used to help determine the etiology of ascites by identifying the presence of portal hypertension.

Serum-Ascites Albumin Gradient (SAAG) = Albserum - Albascites

The presence of a gradient ≥1.1 g/dL or ≥11 g/L indicates that the patient has portal hypertension with 97 percent accuracy. A gradient <1.1 g/dL or <11 g/L indicates that the patient does not have portal hypertension.
