albumin gradient

albumin gradient

A lab value defined as serum albumin minus ascites albumin, which may be useful in linking ascites to portal hypertension. Albumin gradients of >1.1 g/L are typical of transudates, which are usually due to an oncotic pressure gradient between the high systemic arterial pressure and the low ascitic fluid pressure. Albumin gradients of <1.1 g/L occur in exudates which also have high protein levels.

A serum ascites albumin gradient (SAAG) value >1.1g/dl, means that the cause of ascites is most likely to be portal hypertension; this is usually in the setting of cirrhosis.

[5] Hence, several other studies were carried out to propose classifications that included estimation of PF cholesterol, [6,7] ratio of PF/serum cholesterol, PF/serum bilirubin, [7,8] and albumin gradient. [9,10] Later many studies were carried out on adenosine deaminase (ADA), [11,12] which proved that it is a useful biochemical marker to differentiate transudates from exudates.
