Chronic liver disease, especially cirrhosis, is related with ascites. The serum ascites albumin gradient (SAAG), which is based on the difference between the albumin level of serum and of ascitic fluid, may be used to assess the extent of ascites.
Also, 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.
People also ask, why is SAAG high in heart failure?
This balance is disturbed in certain diseases (such as the Budd–Chiari syndrome, heart failure, or liver cirrhosis) that increase the hydrostatic pressure in the circulatory system. The increase in hydrostatic pressure causes more fluid to leave the circulation into the peritoneal space (ascites).
What does SAAG stand for?

Where is albumin made?
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.
How is Budd Chiari syndrome diagnosed?
How is Budd-Chiari syndrome diagnosed? Budd-Chiari syndrome is diagnosed through a physical examination and with certain tests. Your doctor will ask you about your symptoms and will look for signs of Budd-Chiari, such as ascites (swelling in the abdomen).
Why do patients with liver disease get ascites?
Ascites is most commonly caused by a combination of increased pressure in the blood vessels in and around the liver (portal hypertension) and a decrease in liver function.
How do you calculate SAAG?
SAAG is the standard for defining presence of portal hypertension (does not differentiate cause) in patients with ascites. Formula : SAAG = (albumin concentration of serum) – (albumin concentration of ascitic fluid).
