Contributor(s): Yvonne McGrotty

Overview

  • Peritoneal fluid occurs within the abdominal/peritoneal cavity. Very little or no fluid can be aspirated unless effusion is present.
  • Normal fluid is clear and colorless to slightly yellow, and is of low cellularity (<1000 nucleated cells/ml) and protein (<25 g/l).

Methodologies

  • Total nucleated cell count Hematology: leukocyte (WBC).
  • Direct smear.
  • Smear of sediment from centrifuged sample if cellularity is very low.

Availability

  • Widely available at commercial laboratories.

Technique (intrinsic) limitations

  • Sample may be difficult to obtain if only small volumes of peritoneal fluid present.

Technician (extrinsic) limitations

  • Rarely abdominal viscus, eg bowel perforated and fluid collected from extra peritoneal source.
