The high bacterial count in routine urine tests may be caused by 1. urinary tract infections, after the infection, the bacteria multiply abnormally, and then there can be a high bacterial count in the urine, accompanied by frequent urination, urinary urgency, painful urination and so on. The actual results of other items in the urine examination also appear abnormal, such as leukocyte esterase with positive results or an increase in the number of white blood cells, need to further urine bacterial culture examination to confirm the diagnosis. 2, urine is contaminated due to the process of urination, if the urine is contaminated can also appear elevated bacterial count. If you are suffering from circumcision, prepuce, etc., the bacteria on the foreskin will enter the urine and make the bacterial count of the test high, or the contamination of the instrument used to retain urine will lead to a high bacterial count in the urine. Therefore, it is necessary to disinfect or clean the external orifice of the urethra during the urine retention process, and then retain clean middle urine for testing. It is important not to retain the initial and final urine during urination, but to retain the middle urine as much as possible to avoid contamination that may lead to abnormal test results.
