What does urine nitrite have a plus sign for?

The presence of this test in the urine may indicate a bacterial infection. If only this test is abnormal, it is generally not a problem. Other test results in the urine, such as white blood cells and red blood cells, should also be observed. If these test results are abnormal, there is a urinary tract infection. For this situation, it is recommended to take quinolone anti-inflammatory drugs or cephalosporins anti-inflammatory drugs to treat, which can improve the patient's clinical situation.
