Arthrocentesis, or joint aspiration, is the only secure method of evaluating any crystallized deposits in the joints. A sterile needle and syringe are used to remove some of the synovial fluid and determine the source of the deposits causing the pain and swelling. In addition to testing the type of crystals that are present, this fluid can also be tested for white cell count, protein, glucose, or cultured to detect a possible infection.
