Reference Values
An interpretive report will be provided
Interpretation
Peritoneal fluid albumin is used to calculate the serum-ascites albumin gradient. Values of 1.1 g/dL or higher suggest portal hypertension.
Pleural fluid albumin may be used to calculate a serum-effusion albumin gradient. Values above 1.2 g/dL are most consistent with a transudative process.
For all other fluids, the albumin concentration and gradient have only been evaluated in peritoneal and pleural fluids. All other fluid albumin concentrations should be interpreted in conjunction with serum albumin concentration and other clinical findings.
