24-hour pH Probe Study
What is a pH Probe?
A pH PROBE is a 24-hour test that measures the frequency of stomach acid that backs up into the esophagus. It is done as an outpatient procedure and requires no sedation. You or your child will have a small flexible tube passed through one nostril and positioned in the esophagus.

You sound upbeat too.
