Body fluid cell counts by automated methods.

Automated cell counting for body fluids is gradually replacing manual cell counting by hemocytometer. Automation offers potential benefits of improved accuracy, efficiency, and standardization. The addition of body fluid modes to some hematology analyzers adapts the technology and software to meet the particular requirements of body fluid analysis. However, the functional sensitivity for low cell counts currently limits applicability of automated methods to all types of body fluid. Microscopic review is indicated when malignancy is a diagnostic consideration.
