GOUT – INVESTIGATIONS
The following investigations are advised to support the diagnosis:
I. Blood tests :
- Increased blood uric acid levels is the most important sign.
- White blood cell count and ESR may be elevated during an acute attack.
II. X-Ray may show:
- Bone erosion (punched-out lesions) after repeated attacks of gout.
- Tophi in the area surrounding the joint.
- Joint space maybe reduced in later stages.
III. Aspiration of fluid from the joint: Presence of uric acid crystals (mono sodium urate crystals) in the synovial fluid confirms the diagnosis.
