High uric acid may be closely related to gout, hyperuricemia and other diseases, which can be diagnosed and analyzed by X-ray examination, bursa fluid or gout stone content examination, ultrasonography, urinary uric acid test and blood uric acid test. 1. X-ray examination: it is a kind of imaging examination, through which we can determine whether there is gout when uric acid is high, whether there is bone destruction and bone changes, etc. Usually, X-ray examination of gouty joints can be used to determine whether there is gout when uric acid is high. Usually, gouty joint X-ray examination can see soft tissue swelling, cartilage edge destruction, irregular joint surface, and the characteristic changes are puncture-like, worm-like bone defects. 2. Examination of bursal fluid or gout stone content: this examination can clearly diagnose whether high uric acid is related to acute gout attack. Usually, polarized light microscope can see double refractive needle-shaped urate crystals. 3. Ultrasonography: joint ultrasonography can see double track sign or uneven hypoechoic and hypoechoic mixed mass shadow, which is a more specific manifestation of gout. 4. Urine uric acid test: urine can be collected and analyzed after 5 days of purine diet restriction. 5. Blood uric acid test: take fasting venous blood to complete the blood uric acid test. If you find high uric acid, you can understand the cause of high uric acid by completing the above examination and standardize the treatment under the guidance of professional physicians in time to avoid delaying the condition.
