Is there anything else I need to know about a synovial fluid analysis?
Arthrocentesis, the procedure used to do a synovial fluid analysis, may also be done to remove excess fluid from a joint. Normally, there is only a small amount of synovial fluid between the joints. If you have a joint problem, extra fluid can build up, causing pain, stiffness, and inflammation. This procedure can help relieve pain and other symptoms.
