When we get the kidney function test, we should first look at the urea and creatinine, if these two are elevated, the clinical significance is relatively large, elevated suggests that the kidney’s detoxification ability is reduced, which is often referred to as renal failure. The next step is to look for the cause and clarify what exactly is causing the kidney failure, which is likely to develop into uremia if the cause is not clearly identified and not treated. If these two are reduced, generally and poor nutrition has a very big relationship, you can eat more lean meat and eggs, dairy, etc.. Next is to look at uric acid, elevated uric acid can lead to gout and aggravated kidney function, while abnormal kidney function will also lead to elevated uric acid, the two are mutually causal relationship. When uric acid is elevated, you must pay attention to eat less animal offal, drink less beer, and apply uric acid-lowering drugs such as benzbromarone. This test is usually of little significance, but if renal failure is present, this test can identify pre-renal renal failure and renal failure.
