I had mentioned that my boys were having this test this week, but I didn't think to explain it. Here's an explanation:
Impedance pH Testing
Impedance pH is a test to measure the amount of acid and non-acid reflux in the esophagus using a special thin catheter which is passed through the nostrils, down the throat, and remains in the distal esophagus for approximately 24 hours. The catheter is attached to a small monitor worn during the study. It is usually used in the diagnosis of atypical gastroesophageal reflux (GERD) symptoms.
