Blood uric acid 470μmol / L is elevated uric acid, but not necessarily gout, it is recommended to go to the hospital to further improve the examination, a clear diagnosis. Generally non-same day 2 times fasting blood uric acid > 420μmol / L for hyperuricemia, blood uric acid 470μmol / L for uric acid elevation. There is a continuum from hyperuricemia to gout, and a value of 470 μmol/L uric acid alone is not sufficient to diagnose gout. The diagnosis of gout first requires the presence of swelling, pain, or tenderness in at least one peripheral joint or bursa. The gold standard is microscopic examination showing the presence of urate crystals in the affected joint, bursa, or gout stone. If urate crystals are not seen, gout can also be diagnosed when the points in clinical manifestations such as acute arthritic attack, laboratory tests such as high uric acid levels, and imaging features meet the diagnostic criteria for gout. The diagnosis of gout needs to be combined with clinical manifestations and auxiliary examinations, and it is recommended that patients go to the hospital in time for a clear diagnosis and active treatment.
