Test Information
Please arrive 1/2 hour prior to your scheduled appointment.
Do not eat or drink anything for 2 hours before the time of your appointment.
A local anesthetic will be applied inside your nose and throat to make them numb. A small flexible tube will be passed through your nose and down your throat. You will be given water to swallow and help position the tube. Once the tube is in place, you will rapidly adjust to the feeling of the tube. A tiny sensor on the end of the tube will measure the acid in your esophagus.
You will keep the tube in your nose for a period of 24 hours. You will return to the motility lab the following day to have the tube removed.
