Answer

The following studies are used to detect gastroesophageal reflux:

  • Intraesophageal pH probe monitoring: Criterion standard for quantifying gastroesophageal reflux

  • Intraluminal esophageal electrical impedance: For detecting acid and nonacid reflux by measuring retrograde flow in the esophagus; normal values have not been determined in the pediatric age group.

See Workup for more detail.
