Non-inflammatory
LABORATORY FINDINGS IN JOINT DISORDERS
- Clear, yellow fluid
- Good viscosity
- WBCs
- Neutrophils <30%
- Similar to blood glucose
Non-inflammatory
LABORATORY FINDINGS IN JOINT DISORDERS
2 types of inflammatory origin
Immunologic and crystal induced
LABORATORY FINDINGS IN JOINT DISORDERS
- Cloudy, yellow fluid
- Poor viscosity
- WBCs 2,000 to 75,000 uL
- Neutrophils >50%
- Decreased glucose level
- Possible autoantibodies present
Inflammatory (immunologic)
LABORATORY FINDINGS IN JOINT DISORDERS
- Cloudy or milky fluid
- Low viscosity
- WBCs up to 100,000 uL
- Neutrophils <70%
- Decreased glucose level
- Crystals present
Inflammatory (crystal-induced origin)
LABORATORY FINDINGS IN JOINT DISORDERS
Decreased glucose level
Inflammatory (immuno and crystal origin) & septic
LABORATORY FINDINGS IN JOINT DISORDERS
- Cloudy, yellow-green fluid
- Variable viscosity
- WBCs 50,000 to 100,000 uL
- Neutrophils >75%
- Decreased glucose level
- Positive culture and Gram stain
Septic
LABORATORY FINDINGS IN JOINT DISORDERS
- Cloudy, red fluid
- Low viscosity
- WBCs equal to blood
- Neutrophils equal to blood
- Normal glucose level
Hemorrhagic
LABORATORY FINDINGS IN JOINT DISORDERS
Low viscosity
Inflammatory (crystal-induced) & hemorrhagic
