A member asked:
24-hour ambulatory ph test or 24 hour esophageal impedance-ph test. are these the same tests or two different tests?
A doctor has provided 1 answer
Not the same.: The two tests are not the same, but they are carried out very similarly. The impedance portion of the study allows your doctor to determine how much non-acid reflux is occurring. It is an outpatient study involving a very thin tube to pass into your esophagus overnight. It is very useful in determining the best way to treat acid reflux. Good luck.

Had a bravo pH test done, turning in the "pager" unit tomorrow. Any tricks to getting the capsule out of my esophagus quicker? Bit of an annoyance.
