Order Name:
Crystal Synovial Fluid

 
 
Clinical Information:
Birefringent crystals are found in the synovial fluid of more than 90% of patients with acutely inflamed joints.Monosodium urate crystals are seen in gouty fluids and calcium pyrophosphate crystals are seen in chondrocalcinosis. The urates are usually needle-shaped, and the calcium crystals are often rhomboidal. Cholesterol crystals may also be observed.
 
Reference Value:
Not found
 
Interpretation:
Positive identification of crystals provides a definitive diagnosis for joint disease.
