Doctors often diagnose kidney infections based on signs and symptoms, such as fever and back pain.
If your doctor suspects you have a kidney infection, you may be asked to provide a urine sample to test for bacteria, blood or pus is in your urine. Your doctor may also obtain a blood culture — a lab test that checks for bacteria or other organisms in your blood. Other tests might include an ultrasound, computerized tomography scan or a type of X-ray called a voiding cystourethrogram.
