     To Diagnose a Patient with
     Acute Monoarticular Arthritis
   Joint aspiration and inspecting synovial fluid
      or tophaceous material and
      demonstrating characteristic MSU
      crystals (intracellular if joint fluid) is the
      only way to definitively diagnose gout.
      This will also allow gram stain and culture
      to evaluate infectious arthritis.

   Foot radiographs should be done to evaluate
     for possible fracture.

   Serum uric acid level is not helpful in making
     the diagnosis of gout.                                     (c) 1972-2004 American College of Rheumatology
