BMC’s Yawkey building doors are now closed as an entrance as part of our ongoing efforts to enhance our campus and provide you with the best clinical care.

All patients and visitors on our main campus must enter our hospital via Shapiro, Menino, or Moakley buildings, where they will be greeted by team members at a new centralized check-in desk before continuing to the hospital. We are excited to welcome you and appreciate your patience as we improve our facilities.

Esophageal pH/Impedance Probe Study

Select your language:

An esophageal pH test measures the pH, or amount of acid, that flows into the esophagus from the stomach during a 24-hour period. The patient does not need to be in the hospital for this test.
