Blood uric acid testing should be done with the understanding that one blood uric acid value cannot immediately diagnose hyperuricemia, but needs to be tested the next day under normal purine diet, i.e., under the same dietary conditions as usual, rather than under a high purine diet such as hot pot or seafood the day before. The diagnosis of hyperuricemia can only be made after two tests. Hyperuricemia “differs between men and women”. Men with greater than 420 umol/L and women with greater than 360 umol/L are considered hyperuricemic. Once diagnosed with hyperuricemia, it requires long-term management just like controlling blood pressure, blood sugar and blood lipids. Keeping blood uric acid in a stable state for a long time. How high is the blood uric acid level that should be lowered? What is the best level to lower? The answer is different for different cases. The control goals are as follows: after the diagnosis of gout, the control goal of blood uric acid should be lower than the diagnostic criteria, that is, long-term control to <360< span="">μmol/L to maintain below the saturation point of uric acid, and there is evidence that blood uric acid <300< span="">μmol/L will prevent recurrent gout attacks. Therefore, the Chinese Expert Consensus on the Treatment of Hyperuricemia and Gout of the Endocrinology Branch of the Chinese Medical Association recommends starting uric acid-lowering therapy as soon as the diagnosis of gout is established and after the acute symptoms have resolved (≥2 weeks); uric acid-lowering therapy can also be started immediately on the basis of anti-inflammatory therapy in the acute phase to maintain blood uric acid within the target range. Without gout but with cardiovascular risk factors and hyperuricemia, men >420 μmol/L, women >360 μmol/L start intervention, 3-6 months diet therapy is ineffective, uric acid-lowering drugs should be given; without gout and cardiovascular risk factors, men >420 μmol/L, women >360 μmol/L but <540 umol/L diet therapy for 3-6 months, ineffective Uric acid-lowering drugs should be given; blood uric acid >540 umol/L must be treated with both diet therapy + uric acid-lowering drugs to bring blood uric acid down to normal level. It should be noted that uric acid-lowering therapy should be started after the gout is in remission, otherwise it will aggravate the gout.
