Part Description

LP157160-5   Albumin.serum-albumin.periton fld
The serum-ascites albumin gradient (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. The formula is as follows:

SAAG = (albumin concentration of serum) - (albumin concentration of ascitic [peritoneal] fluid).

Ideally, the two values should be measured at the same time. A high gradient (> 1.1 g/dL) indicates the ascites is due to portal hypertension with 97% accuracy. Important causes of high SAAG ascites include: 1) high protein (> 2.5) which can lead to heart failure, and 2) low protein (< 2.5) which can lead to cirrhosis of the liver (Budd Chiari syndrome). A low gradient (< 1.1 g/dL ) indicates causes of ascites not associated with increased portal pressure, including nephrotic syndrome, tuberculosis, and various types of cancer.
