Background

The urine examination comprises routine analysis of urine, detection of visible components in urine (such as urine red blood cells, white blood cells and the like), quantitative determination of protein components, and urease determination. Urine tests have important values for clinical diagnosis, judgment of curative effect and prognosis. Urine routine examination notes: 1. when the urine is regularly checked, not less than 10 ml of urine is left. 2. It is better to leave the midcourse urine, because the forepart urine and the rear part urine are easy to be polluted, so the midcourse urine is generally left when the routine urine examination and the urine bacteriological examination are performed. 3. The retained urine should be sent to the laboratory for examination as soon as possible, because glucose is decomposed by bacteria and cell lysis occurs after a long time, which affects the accuracy of the examination result. Therefore, when the urine routine examination is performed, the correct specification of collecting the urine specimen is paid attention to, and the key for ensuring the accuracy of the urine routine examination result is. At present, the urine is generally taken by adopting a hand-held disposable urine cup, on one hand, the urine taking amount is not easy to control, and the urine taking amount is easy to cause too much; on the other hand, the midstream urine is inconvenient to accurately collect, and in addition, the urine is easy to splash, which is very inconvenient and unsanitary.
