Ascites fluid analysis.
To evaluate and classify the type of fluid within the peritoneal cavity to assist with diagnosis of cancer, infection, necrosis, and perforation.
Peritoneal fluid collected in a red- or green-top (heparin) tube for amylase, glucose, and alkaline phosphatase; lavender-top (EDTA) tube for cell count; sterile containers for microbiology specimens; fluid in a clear container with anticoagulant for cytology. Ensure that there is an equal amount of fixative and fluid in the container for cytology.
(Method: Spectrophotometry for glucose, amylase, and alkaline phosphatase; automated or manual cell count, macroscopic examination of cultured organisms, and microscopic examination of specimen for microbiology and cytology; microscopic examination of cultured microorganisms)
