Pleural fluid: analysis

Contributor(s): Yvonne McGrotty

Overview

  • The pleural cavity normally contains only a small amount of fluid; little or no fluid can be obtained by aspiration unless excess fluid (pleural effusion Pleural: effusion ) is present.
  • Gross appearance of the fluid can provide information which may assist in determining the nature of the fluid, eg a milky solution may be chylous.
  • Investigation of effusions commonly includes some or all of the following:
  • Additional biochemical analyses may be of benefit for further characterization. Aim to classify effusion initially into:
    • Transudate.
    • Modified transudate.
    • Exudate.
