Interpretation
Pleural: Serum- pleural fluid albumin gradients of >1.2 g/dL are consistent with transudates.
Peritoneal: Serum-ascites albumin gradient (SAAG) of 1.1 g/dL or greater suggests portal hypertension.
Pericardial: The reference range has not been established for this fluid specimen. The fluid results should be compared with the concentration in serum/plasma or integrated into the clinical context for interpretation.
