CELL COUNT WITH DIFFERENTIAL, BODY FLUID
Geisinger Epic Procedure Code: LAB1971 Geisinger Epic ID: 7683Pericardial fluid, peritoneal (ascitic) fluid, pleural, amniotic fluid, and other serous fluids (non-synovial)
2-3 mL (preferred), 1 mL (minimum)
Indicate specimen source on label and requisition. Clotted and partially clotted specimens will receive a comment, "Fluid clotted cell count questionable". Fluids received in sodium heparin tubes will receive a comment, "Specimen received in heparin anticoagulant which may cause lower WBC counts."
Do not centrifuge or freeze.
Refrigerated.
24 hours.
BAL specimens, gastric specimens, and semen analysis specimens. Specimen sent with needle. Frozen specimens. Clotted specimens.
Varies based on specimen type.
Red cells are increased in trauma and hemorrhage.
White blood cells are increased in inflammatory and infectious processes:
- neutrophils predominate in bacterial infections
- lymphocytes predominate in viral infection
- macrophages may be increased in inflammatory and infectious processes
- eosinophils may be increased in parasitic or fungal infections.

Color, Clarity, Total nucleated cell count (TNC) (Note: This includes WBC count and other nucleated cells including epithelial cells, histiocytes, macrophages, mesothelial cells etc.) , RBC, TNC differential = % of each cell type in 100 total nucleated cells.
Electronic resistance detection enhanced by hydrodynamic focusing and flow cytometry
Hemocytometer
Microscopic Examination
BFCD, BFC, cell count FLD
Quantitative determination of cells including WBCs, RBCs, and lining cells in various body fluids (excluding bronchoalveolar lavage specimens), which aids in the diagnoses of systemic disease, inflammation, malignancy, infection, and trauma.
