Doctors may use urine tests to check if your child’s liver or kidneys are working properly. Tumour markers may also show up in a urine test.
Your child will need to urinate (wee) into a plastic cup. If your child is not yet toilet trained, you can use a special bag that can be placed in their nappy to collect the urine.
The urine sample is tested in a laboratory, and the results may take a few days to come back.
