A clean-catch urine sample is needed. This is often done at your doctor's office or health clinic.

No special preparations are necessary. Make sure your doctor knows about all the medicines you or your child are taking or have recently used. If this test is being done on an infant who is breast-feeding, make sure the health care provider knows what medicines the nursing mother is taking.
