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.

These studies identify age, sex, blood neutrophil-to-lymphocyte ratio (NLR), serum albumin level, serum lactate dehydrogenase (LDH) level, ascites parameters, and the serum-ascites albumin gradient that may be associated with the prognosis of patients with multiple tumors [4-8].
Ascites was noted on physical exam, and the patient underwent a diagnostic paracentesis that revealed a serum ascites albumin gradient of <1.1, polymorphonuclear cell count <250/[mm.sup.3], and negative culture.
Several laboratory test results such as elevated levels of LDH, total protein, adenosine deaminase, and lymphocyte count; low serum-ascites albumin gradient; cytological examination, and decreased glucose level of the ascitic fluid help in the distinction of these diseases.

[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.
