Serum-ascites albumin gradient (SAAG) is more useful than the total protein concentration of ascitic fluid in the classification of ascites. This gradient is physiologically based on oncotic-hydrostatic balance and is related directly to portal pressure.
Moreover, what is SAAG paracentesis?
The serum-ascites albumin gradient or gap (SAAG) is a calculation used in medicine to help determine the cause of ascites. The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate.
Thereof, what causes low SAAG?
Low SAAG ascites (<1.1 g/dL) is usually caused by peritoneal malignancies, chronic peritoneal infection (i.e., mycobacterium tuberculosis), and nephrotic syndrome. Cancers that spread to the omentum and result in ascites are typically of ovarian, gastric, or pancreatic origin.
Is ascites a transudate or exudate?
Ascites is usually considered to be an ex- udate or transudate. Exudative ascites can be secondary to malignancy, infection, or inflammation, whereas transudative ascites can be due to portal hypertension, congestive heart failure or hypoalbuminemia [14].
