If in the early healthy people, we advocate that we should go for a checkup as early as possible, because chronic kidney disease is an insidious disease in the early stage, there may not be any discomfort, so it is recommended that people over 35 years old should do three tests every two years: 1, urine test, also known as routine urine test; 2, blood test for kidney function, including blood creatinine, blood urea nitrogen and uric acid kidney function of the three conditions; 3, the third test is that you can do A kidney ultrasound to see if there are stones and occupying lesions in the kidneys, ureter and bladder. If these three tests are okay, it proves that your kidneys are already in good condition. If there is a problem inside these three tests, you may need to go to a specialist for further evaluation. If the problem persists for more than 3 months, we can diagnose it as chronic kidney disease. These three tests are complicated to say the least, but the tests are non-invasive and very inexpensive, you can solve the problem for about 100 RMB or less in Guangzhou.
