What is SAAG test?

The serum-ascites albumin gradient (SAAG) is necessary to determine if a patient’s ascites is due to portal hypertension. ▪ Calculation of SAAG is performed by measuring the serum albumin and ascitic fluid albumin concentrations simultaneously and then subtracting the ascitic fluid albumin from the serum albumin.

Just so, what does a SAAG score mean?

The SAAG is a physiological clinical diagnostic tool for the evaluation of ascites. An increased SAAG (> 1.1 gm/dL) value indicates the presence of portal hypertension, which is detected by observing portal hypertensive changes in the upper gastrointestinal tract.

Hereof, what does a low SAAG mean? > lang=”en”>>A low gradient (SAAG < 1.1 g/dL) indicates nonportal hypertension and suggests a peritoneal cause of ascites. Such conditions may include the following: Primary peritoneal mesothelioma. Secondary peritoneal carcinomatosis.>>>

Accordingly, what is the normal SAAG?

Under normal circumstances the SAAG is < 1.1 because serum oncotic pressure (pulling fluid back into circulation) is exactly counterbalanced by the serum hydrostatic pressure (which pushes fluid out of the circulatory system).

What is low SAAG ascites?

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.

How do you interpret a SAAG ratio?

A high SAAG (>1.1g/dL) suggests the ascitic fluid is a transudate

  1. Malignancy.
  2. Infection.
  3. Pancreatitis.
  4. Nephrotic syndrome.

What is SAAG in ascitic fluid?

Defines presence of portal hypertension in patients with ascites.
