What Is Pyelonephritis?
3. How Is Pyelonephritis Diagnosed?
If your doctor suspects that you have a kidney infection, he or she will have you provide a urine sample to check for bacteria in your urine. Blood tests may also be necessary to see if your body is fighting an infection.
If nothing shows up in your urine or bloodwork, or if your doctor still needs more information, you may undergo an ultrasound of your kidneys. Another test called a “voiding cystourethogram,” during which a contrast dye is injected into your bladder before X-rays are taken, is also available for severe or difficult-to-diagnose cases.
