Test Code BFCELA Cell Count with Differential, Body Fluid, Automated

Infectious

Additional Codes

EPIC LAB4365

NOTE: BFCELL is available in Sunquest for manual body fluid cell counts if unable to perform an automated cell count.

Purpose

Body fluids such as ascities, pleural, and synovial fluids are sampled by aspiration and tested when they show abnormal accumulation. Such tests provide important information for differential diagnosis by the physicians. The white blood cell count and classification of cells in body fluids and puncture fluids can be used by the physician for ascertain the pathophysiology of inflammation and tumors, and for making definitive diagnosis, as they indicate the causes of the pathological retention.
