  • Pericardial fluid analysis: to evaluate and classify the type of fluid between the pericardium membranes to assist with diagnosis of infection or fluid balance disorder.
  • Specimen: Pericardial fluid collected in a red- or green-top (heparin) tube for glucose, a lavender-top (EDTA) tube for cell count, and sterile containers for microbiology specimens; fluid in a clear container for cytology. Ensure that there is an equal amount of fixative and fluid in the container for cytology.
  • Method: Spectrophotometry for glucose; automated or manual cell count, macroscopic examination of cultured organisms, and microscopic examination of specimen for microbiology and cytology; microscopic examination of cultured microorganisms.
