Serum Ascites Albumin Gradient (SAAG)

Formal Name: 

Serum Ascites Albumin Gradient (SAAG)

Why to Get Tested:

The serum-ascites albumin gradient or gap (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.
