What will happen during this H. Pylori breath test?

This test is short and pain free.

  • First, a nurse will ask your child to blow into a small bag. This will be the “baseline” breath sample.
  • Then the nurse will ask your child to drink a special liquid through a straw.
  • After 15 minutes the nurse will ask your child to blow into another bag. This will be the “test” breath sample. Both of these breath samples will be sent to special lab for testing.

The lab will send your doctor a report with your child’s test results in about a week. After you leave our office, your child may have liquids, food, and medicines as normal.

Please call the doctor’s nurse at 214-456-8000 or the GI Lab at 214-456-7857 if you have questions.
