It is recommended that you do not drink excessively or intentionally drink less water the day before the test, so that you can achieve an optimal test result. For uric acid, it is mainly metabolized in the kidneys. Many patients, because of long-term eating of various foods with high purine, such as various animal offal, various hot pot, strong tea, spinach, etc., can lead to elevated uric acid. It is recommended that you should drink more water, eat less of various animal offal, and take oral allopurinol and sodium bicarbonate if necessary, which can lower uric acid.
