High uric acid in blood test indicates high urate content in the body, indicating hyperuricemia. Patients may show symptoms such as redness, swelling, heat and pain in the joints, and in severe cases, joint mobility may be impaired. High uric acid in the blood is caused by the body consuming too much soy, seafood, beef and mutton, which contain too much purine substances, thus leading to high uric acid in the blood.

In addition, patients also need to pay attention to their diet, which should be light.
