What a 24 Hour Multichannel pH and Impedance Testing Looks Like

I often order a special test called "24 hour Multichannel pH and Impedance Testing" when working up patients with symptoms of chronic cough, globus, phlegmy throat, and/or throat clearing.

This test measures any non-acid and well as acid reflux along with muscle contractility of the esophagus continuously over a 24 hour period of time.

The catch is that a catheter needs to be placed through the nose and into the stomach AND left in place for 24 hours. Patients often ask what this looks like... so here's a picture!
