Cell counts, WBC differential and morphology reports from cytospin preparations are performed on body fluids to assess for infection or haematological malignancy.

Fluid types include CSF, Ascetic Fluid, PD fluid, Synovial fluid, and pleural fluid. 

 

 CSF counts and cytospin for suspected haematological malignancy

CSF screening for trypanosomiasis

Cell counts including WBC and differential counts of neutrophils, mononuclear cells and eosinophils on Ascetic fluid, Pleural fluid, Synovial fluid/Knee aspirates, PD fluids for suspected infection.

 

Note: Body fluids for suspected malignancy and joint fluid crystals should be sent to cytology

CSF counts for suspected meningitis should be sent to microbiology

Please refer to Trust protocol for CSF counts in suspected SAH
