Instructions for Testing


An anorectal manometry is a test to measure how your child’s muscles and nerves work inside the rectum.  A small, soft, flexible tube with a small balloon on the end is used.

An antroduodenal manometry is a test to measure how your child’s muscles and nerves work inside the stomach and small bowel.  This is a two day test that requires an overnight stay in the hospital.

The test involves a miniature pH capsule, about the size of a gel cap that is placed on the wall of your child’s esophagus.  The capsule measures the pH (acid level) in the esophagus and transmits the information to a receiver about the size of pager that is worn around the waist.

A colonic manometry is a test to measure how your child’s muscles and nerves work inside the colon.   This is a three day test that requires an overnight stay in the hospital.  On the first day, your child will have a colonic cleanout (removal of stool) often via a tube placed in your child’s nose.

An impedance study is a test to find out if contents from the stomach are coming up into the esophagus.  The test lasts 18-24 hours.

Hydrogen breath test is a simple way to measure whether your child can digest sugar. This may be the sugar in milk (lactose), table sugar (sucrose), or the sugar in the fruit (fructose). It may also be used to test for a problem called bacterial overgrowth.
