The uric acid test generally requires fasting, which can make the test results more accurate, and is usually suitable for the detection of gout disease and the early diagnosis of kidney disease.
Uric acid is the end product of purine metabolism. If there is a disorder of purine metabolism or abnormal energy metabolism, and the renal excretion of uric acid is hindered, the plasma uric acid concentration may increase, resulting in hyperuricemia. The uric acid test can effectively determine whether you have gout. In addition, if you have kidney disease, you may have high uric acid in the early stage. For the uric acid test, a blood test is usually selected. If you eat high-purine food such as animal offal or seafood before the uric acid test, the purine content in the blood will increase, which will affect the uric acid test result, and may also affect the medical condition. Misdiagnosis occurs, so fasting is required before the uric acid test to make the test results more accurate.
