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.
Besides, what does high SAAG mean?
A high gradient (SAAG >1.1 g/dL) indicates portal hypertension and suggests a nonperitoneal cause of ascites. Such conditions may include the following: Cirrhosis. Fulminant hepatic failure.
In respect to this, what is the SAAG in SBP?
The serum-ascites albumin gradient (SAAG) helps determine whether peritoneal fluid is a transudate or exudate. Theoretically it might also be helpful in the diagnosis of SBP, as the ascitic fluid would normally be expected to have a relatively high protein level.
What SAAG means?
How do you read SAAG?
A high SAAG (>1.1g/dL) suggests the ascitic fluid is a transudate
- Malignancy.
- Infection.
- Pancreatitis.
- Nephrotic syndrome.
Can SAAG be negative?
Diagnostic accuracy, Sensitivity, Specificity, Positive predictive value (PPV) and Negative predictive value (NPV) of SAAG were 96%, 97%, 95%, 98.6%, and 90% respectively, whereas those of AFTP were 56%, 53%,70%, 86%, and 29% respectively.
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].
