24-Hour Esophageal pH Study

A 24-hour esophageal pH study measures how much stomach acid backs up into the food pipe in 24 hours. The most common uses for this gold standard test are:

  • To diagnose gastroesophageal reflux disease (GERD, a feeling of heartburn, pain and food coming back up)
  • For patients with other problems (such as atypical chest pain, recurring pneumonia or throat symptoms)
  • Pretreatment and post-treatment evaluation to determine if medication dosage is correct
  • For presurgical and postsurgical heartburn
  • For non-cardiac chest pain
