When a routine urine test is performed for a urinary tract infection, the test is negative if the infection has been cured, so a negative test is a sign of cure. If the infection has not been cured, it is positive, so a positive test indicates that the infection is still in progress. If the test is still positive, you should continue to follow the same treatment plan. If the patient’s symptoms of frequent urination, urgent urination, and painful urination have disappeared, the patient should go to the hospital for a laboratory test at this time, and if the test is negative, there is no need to continue taking oral medication, indicating that the patient is cured, which is the best result. If the self-conscious symptoms disappear but the test is still positive, the pathogenic bacteria latent in the body has not been completely cleared and the urine still shows a positive result, so it is necessary to continue with the medication. Even if the patient does not have any conscious symptoms at this time, it can still lead to a recurrence of symptoms if the medication is rashly stopped later.
