Tests & Diagnosis
In order to determine if your symptoms are indicative of gout, analysis of your synovial fluid is required, which will show the presence (if any) of monosodium urate crystals.
It is also possible that your doctor may order a blood test, which could reveal elevated inflammatory markers, and other factors that can indicate gout.
To determine whether the cause of gout is due to over-production (excessive uric acid) or under-excretion (inability to get rid of uric acid), a urine test may be ordered by your doctor.
When gout becomes chronic, x-rays can reveal irregularities in soft tissue and bone, especially calcification from uric acid crystals, bone erosion, and reduction in joint space.
Gout is diagnosed clinically, based on signs, symptoms and laboratory findings; other (differential) diagnoses must be ruled out, due to their association with hyperuricemia:
- Alcohol abuse
- Drug use
- Kidney dysfunction and disease
- Diseases and disorders of the blood, bone marrow and immune system
- Certain types of diabetes and anemia
