You will be asked by your doctor or nurse to collect a urine sample from your child. This needs to be done in a very clean way and the urine collected in a special sterile urine pot. Once the urine is collected in such a way, this will be tested straight away by a urine dipstick test and will also be sent to the lab for further analysis to confirm the diagnosis. Your doctor will be able to tell you if the initial test suggest an infection and advise you on what to do. The lab analysis usually takes up to 2 days for the results to come back.
