Input
 

Serum Albumin		g/L g/dL gm/L gm/dL mg/L mg/dL
Ascites Albumin		g/L g/dL gm/L gm/dL mg/L mg/dL

 
Result
 
Important: Inputs must be complete to perform calculation.

 

SAAG		g/L g/dL gm/L gm/dL mg/L mg/dL
Decimal Precision   0 1 2 3

 

SAAG Interpretation

 

SAAG (g/dL) <1.1:	Consistent with carcinomatosis, tuberculosis, pancreatitis, serositis, or nephrosis
SAAG (g/dL) >=1.1:	Consistent with portal hypertension, CHF or Budd-Chiari syndrome
