Pharyngeal pH Measurement
What is a pH test?
The Restech Dx-pH Test is a diagnostic test to determine the amount of acid reaching your airway. It is a simple, comfortable test performed with a small probe containing a sensor at the tip. It is placed through the nose until the tip is at the back of the throat- high enough so you cannot feel it when you speak or swallow. The sensor collects pH data and sends it to a small recorder worn on your belt or over your shoulder.
During the test period (typically 24 to 48 hours), you can eat normal meals, go to work, and even exercise. The Dx-System charts pH levels to document when reflux occurs most frequently, and monitors the severity. With your input, the Dx-System tracks meals, symptoms, and supine periods. This information helps correlate symptoms and reflux patterns and will assist Dr. Anderson as she creates your treatment plan.
