In addition to pathological conditions, abnormal urine routine indicators may also have the problem of specimen contamination. In either case, once the urine routine white blood cell abnormalities are found, they must be rechecked several times to exclude abnormal results due to urine contamination on the one hand, and to compare the changes in the indicators on the other hand, while combining other examination items to find the cause and then consider treatment options.
