To do a uric acid test, an empty stomach is required. Uric acid is a product of purine metabolism, and its normal value in the human body is affected by the production of uric acid and the excretion of uric acid. Hyperuricemia is not good for the kidneys, mainly through the three mechanisms of hyperuricemia nephropathy, gouty nephropathy, and nephrolithiasis, which damage the kidneys. Therefore, patients with hyperuricemia are generally required to reduce to normal levels.
The method of judging the normal level is to monitor blood uric acid first. The monitoring of blood uric acid is also affected by many factors. Eating foods high in purines may increase blood uric acid levels. If you drink more water, it will cause the blood uric acid level to drop. If after eating, the level of blood uric acid may increase or decrease, so it is not accurate enough to check, so the test of uric acid also requires fasting.
