Mid esophageal pH-metry The “gold standard” test of
GER is pH esophageal monitoring.
The ph probe in the
esophagus is attached to the pH monitor for a 24 hour period during which
infant care is unchanged from normal (i.e. ambulatory test).
The duration of GER, the number of episodes of GER and the pH level in
the esophagus during these periods are recorded.
The effect of feeding, medications etc. is noted.
The clinical changes e.g. vomiting, apnea etc. is recorded.
