Test Overview
Test Methodology

Sysmex XN9000 for automated cell counts.
Manual hemocytometer cell counts and manual cytospin differential preparations.

Test Usage

Evaluation of body fluids for a variety of disease states.

Reference Range *

Synovial Fluid Counts:
WBC: <150/uL

Synovial Fluid Differentials:
Neutrophils: <25%
Lymphocytes: <75%
Histiocytes: <70%

No Reference Intervals are defined for non-synovial counts and differentials.
