Albumin Peritoneal Fluid: Because of the wide range of albumin levels seen in serous body fluids, results are best evaluated by using the serum-ascites albumin gradient. A serum-ascites albumin gradient of equal to or greater than 1.1 g/dL predicts portal hypertension with 97-98% accuracy and is seen in conditions such as cirrhosis, congestive heart failure and portal vein thrombosis. Gradients less than 1.1 g/dL are associated with ascites due to exudates (e.g. inflammation, infection and malignancy).
Pleural Fluid: Serum albumin-pleural fluid albumin gradient of less than or equal to 1.2 g/dL is consistent with exudate.
