High uric acid is positively correlated with gout attacks, but there is no specific blood uric acid value that causes gout attacks, and there is some individual variation. Hyperuricemia can be diagnosed in men with blood uric acid >420umol/L and in women >357umol/L. Hyperuricemia is the basis for the development of gout, but elevated blood uric acid alone does not equate to gout, which must occur with the precipitation and with the deposition of urate crystals. Patients with elevated blood uric acid alone may not show any discomfort, but only a persistent or fluctuating increase in blood uric acid. Many patients do not even know that their blood uric acid is elevated if they do not have a blood test. Patients with hyperuricemia are at high risk for gout attacks. Gender, age, history of hyperuricemia, and blood uric acid levels all combine to determine whether a gout attack will occur and how early it will occur. In male patients, the older they are, the longer their history of hyperuricemia and the higher their blood uric acid levels, the greater the likelihood of gout attack. The longer the history of hyperuricemia and the higher the blood uric acid level, the greater the likelihood of uric acid crystal precipitation and deposition. This shows that there is individual variability in gout attacks, and there is no specific blood uric acid value that causes a gout attack. However, hyperuricemia is the basis of a gout attack. Patients with hyperuricemia should seek prompt medical attention and intervene to prevent gout attacks through diet, exercise, or through medication.
