Answer

Synovial fluid should also be sent for cell count. During acute attacks, the synovial fluid is inflammatory, with a WBC count higher than 2000/µL (class II fluid) and possibly higher than 50,000/µL, with a predominance of polymorphonuclear neutrophils, though low WBC counts are occasionally found.
