Reference range is not defined; other clinical data should be taken into consideration when interpreting these results.

  • Peritoneal fluid Total Protein >3 g/dL may indicate transudates while fluid Total Protein <3 g/dL may indicate exudates.  Serum ascites albumin gradient measurement is now preferred.
  • A pleural fluid/serum ratio >0.5 suggests an exudate.  Pleural effusions related to Waldenstrom's macroglobulinemia and multiple myeloma typically have protein concentrations from 7.0-8.0 g/dL
