The diagnosis of gout is based on the typical symptoms of gout, such as redness, swelling, pain, increased skin temperature and restricted movement of the joints, together with blood tests for uric acid. Most gout patients have high blood uric acid, but some patients may have normal uric acid or mildly increased uric acid during the acute attack of gout. At this point, the diagnosis of gout is not negated, and further examination of musculoskeletal ultrasound of the joints or MRI of the involved areas can be performed to further clarify the diagnosis. The urine test is mainly to check the 24-hour uric acid, and the test can understand the specific type of uric acid increase, so as to clarify the selection of appropriate medication for treatment during the gout remission period. For example, if the 24-hour uric acid is more than 600mg, you can choose a drug to inhibit uric acid production for treatment. If the 24-hour uric acid is less than 600mg, you can choose drugs to promote uric acid excretion for treatment.
