To confirm that you have a kidney infection, you'll likely be asked to provide a urine sample to test for bacteria, blood or pus in your urine. Your doctor might also take a blood sample for a culture — a lab test that checks for bacteria or other organisms in your blood.
Other tests might include an ultrasound, CT scan or a type of X-ray called a voiding cystourethrogram. A voiding cystourethrogram involves injecting a contrast dye to take X-rays of the bladder when full and while urinating.
