The specimens retained are different, urinary routine requires the retention of the patient’s urine for laboratory tests, while renal function requires the retention of fasting blood for relevant laboratory tests. 2. The items examined are different, urinary routine is only a basic screening test, reflecting the basic condition of urine, such as acidity or alkalinity or whether there are elevated numbers of white blood cells and red blood cells in the urine, whether there is The kidney function test contains urea nitrogen, creatinine and other kidney filtration indicators, which can directly reflect the filtration function of the kidneys and can be used to determine whether the kidney function is in a normal state, while the kidney function test is a quantitative test that can measure the specific kidney function values for detailed assessment. 3, the significance of the two is different, urinary routine abnormalities often suggest that there may be infection in the urinary tract, or there is bleeding, or there is kidney damage, is a more extensive or coarse examination; kidney function test items are more refined, can directly judge the filtration function of the kidneys, to determine whether the kidneys are in a normal state of work, is a more accurate test.
