A Differential Cell Count is a cytology test whereas a Cell Count is a Microbiology test* (See Below).
For Pleural fluids, Pericardial fluids and Ascitic fluids, a Differential Cell Count determines the relative percentage of each type of white blood cell, including neutrophils, lymphocytes and eosinophils.
For CSF(Cerebrospinal fluids) and Peritoneal Dialysis Fluids (PDF), a Differential Cell Count determines the relative percentage of each type of white blood cell, including neutrophils, lymphocytes and eosinophils, in 0.5 mL of fluid. This is expressed as a number of cells per 0.5 mL of fluid.
A differential cell count can also detect abnormal white blood cell populations (eg, blasts, immature granulocytes, or circulating lymphoma cells in the fluid and abnormalities/malignancies.
*A Cell Count (performed in Microbiology), measures the number of white blood cells and red blood cells in the fluid, and are usually expressed as a number of cells per unit of volume.
