Dynamic position versus 24-hour pH testing for detection of esophageal acid reflux disease.
Although the 24-hour pH test is currently considered the gold standard for the determination of significant esophageal acid reflux disease, it is a problematic study, requiring multiple manipulations for interpretation. Dynamic position testing has recently been described as an alternative method of detecting significant esophageal acid reflux disease. In this initial comparative study, dynamic position testing was at least as reliable as 24-hour pH testing, required much less time, and provided additional useful information.
