A SAAG value of 1.2 g/dL indicates ascites due to which cause?

Explanation:
SAAG stands for the serum‑ascites albumin gradient and is used to distinguish ascites caused by portal hypertension from other etiologies. It’s calculated by subtracting the ascitic fluid albumin from the serum albumin. A SAAG of 1.1 g/dL or higher points to portal hypertension as the cause, because the ascitic fluid in these cases is largely a transudate driven by increased hydrostatic pressure in the portal system, resulting in a relatively higher gradient. In contrast, ascites from malignancy, infection, nephrotic syndrome, or other non‑portal hypertensive processes typically yields a SAAG below 1.1 g/dL due to higher protein content in the fluid. Therefore, a SAAG of 1.2 g/dL indicates portal hypertension as the underlying cause.
