For example, the presence of urine glucose (+) suggests high blood sugar, a common cause of diabetes. If urine leukocytes (+) are present, it usually indicates a urinary tract infection. The presence of urine protein occult blood (+) is often due to kidney-related diseases, such as nephritis, and requires analysis of the condition according to the specific abnormal items, so that a treatment plan can be tailored. Urine routine is a routine clinical test that is mainly used to detect early kidney diseases. In the early stage of many kidney diseases, patients do not show obvious symptoms of discomfort, but can show abnormal urine tests. Through active treatment at this stage, the disease can be effectively prevented from deteriorating.
