Before you come to the hospital, explain to your child what will happen. For young children, use simple words and explain only shortly before the test.
On the day before the test, your child may have nothing but clear liquids all day. Your child should not eat any solid food, and may drink only clear liquids. Clear liquids include water, broth, clear juices such as apple, cranberry and fruit punch, Kool-Aid or soft drinks. If your child is taking medicine ordered by a doctor, give it at the scheduled times. Milk, chewing gum, hard candy or mints should not be given to your child.
Before the test, your child will need to drink two doses of an over-the-counter laxative such as magnesium citrate, which can be purchased at a pharmacy or drug store. If your child will be coming to Cincinnati Children's as an outpatient for this test, give the magnesium citrate at 3 pm (or after school) on the day before the test, and again at bedtime the night before the test. Follow the directions below for the amount to give.
|Child's Age ||Dose |
|Under 1 year||No laxative|
|1 - 3 years||1½ ounces|
|3 - 5 years||2½ ounces|
|6 - 8 years||3 ounces|
|9 - 12 years||4 ounces|
|13 - 18 years||5 ounces|
On the day of the test, your child should not eat or drink anything for 4 hours before the test.
