The Serum Ascites Albumin Gradient (SAAG) defines presence of portal hypertension (does not differentiate cause) in patients with ascites.

The serum-ascites albumin gradient or gap (SAAG) is a calculation used in medicine to help determine the cause of ascites. [1] The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate. [2] The formula is as follows: SAAG = (serum albumin) − (albumin level of ascitic fluid).

2018年7月2日 · The serum ascitic albumin gradient (SAAG) indirectly measures portal pressure and can be used to determine if ascites is due to portal hypertension. A high SAAG (>11 g/L) suggests the ascitic fluid is a transudate. A low SAAG (<11 g/L) suggests the ascitic fluid is …

This Serum Ascites Albumin Gradient (SAAG) calculator determines the gradient between the circulatory and ascetic fluid albumin to find if is caused by portal hypertension. There is in depth information below the form on the albumin concentrations and what the gradient results mean.

Management of adult patients with ascites due to cirrhosis: update 2012. This calculator operates entirely from your device. No input variables or data is transmitted between your computer and our servers. The following values can be set in this form: serum, ascites. Set them using the # (hash) at the end of the URL.

The SAAG calculator will help you identify the probable cause of ascites (abnormal fluid in the peritoneal cavity).

The ascites albumin gradient calculator requires three variables: the serum and ascites albumin values, which can be input in several measurement units (g/dL, g/L, mcg/dL) and the desired measurement unit for SAAG.

The serum ascites albumin gradient (SAAG) is a formula used to assist in determining the etiology of ascites. Low Gradient (<1.1g/dL) suggests ascites NOT caused by portal hypertension. Source: Hoefs JC. The mechanism of ascitic fluid protein concentration increase during diuresis in patients with chronic liver disease.

The calculation of the Serum-Ascites Albumin Gradient (SAAG) helps to clarify the source of ascites. An elevated gradient (> 1.1 g/dL) suggests that ascites is caused by portal hypertension, commonly associated with cirrhosis, Budd-Chiari syndrome, and heart failure.
