The doctor or nurse will ask a urine sample of the daughter for lab analysis to check for bacteria, red blood cells or white blood cells. Sometimes after the urine lab analysis it will be followed by a urine culture.

If the daughter is having frequent infections or low grade fever that the doctor concludes that it may have been caused by an abnormality in the urinary tract, she may have a magnetic resonance imaging (MRI), a computerized tomography (CT) scan or ultrasound.
