Routine urine examination is the simplest and cheapest test of the urinary system, but it is also the quickest way to determine urinary system diseases. In municipal tertiary hospitals, there are two types of routine urine tests: 1) the normal dry chemistry test, which costs$8; 2) the urine sediment test, which costs$25. Urine sediment test is to take urine for centrifugal sedimentation and then make quantitative analysis of the sediment, which is more accurate than the urine dry chemistry test, but the price is also slightly higher. In general, urine sediment tests are not available in municipal level II hospitals or level I hospitals, and are usually done as a routine dry chemistry test. The results of the urine sediment test will be available in about half an hour after the test, and the results of the urine dry chemistry program test will be available in about ten minutes, which can initially determine whether there are bleeding disorders and infectious diseases in the urinary system.
