Exercise 7

The following results were obtained on a peritoneal fluid:serum albumin, 2.8 g/dL; fluid albumin, 1.2 g/dL.

a. Calculate the SAAG.

b. Is this a transudate or an exudate? Why?

c. What is the most probable cause of the effusion?

Step 1 of 3

a.

Calculation of SAAG -Serum-Ascites Albumin Gradient:

Formula to find the SAAG is given below,

Substitute the value “2.8 g/dL” for “albumin level of serum” and “1.2 g/dL” for “albumin level of fluid” in above formula.

Therefore, the gradient (difference) of SAAG is.
