White blood cells, commonly known as white blood cells, are very important blood cells in human blood. White blood cells shoulder many important tasks in the human body, with the functions of swallowing foreign bodies, producing antibodies, healing body injuries, resisting pathogen invasion, and immune resistance to diseases. People's physical discomfort is often manifested as a significant change in the number of white blood cells. The results of routine urine examination show that the white blood cells are +- 15 cells/ul, which should be automatically detected by machine. White blood cell+-indicates that it is suspicious. It is necessary to take a urine sample for microscopic examination to determine whether there are white blood cells in the urine and the number of white blood cells contained.

Normal people's urine sediment microscopic examination of white blood cells does not exceed 5/ high vision, and if it exceeds 5/ high vision, it will increase. This is called microscopic pyuria, which has clinical significance. Such as pyelonephritis, cystitis and urethritis. Urine dry chemical analysis: white blood cell (particle) reference value: negative.

Urine sediment analysis: white blood cell count reference value: 0.00-25.00/ul.
