Problems with using pH testing for diagnosing Gastroesophageal reflux disease

There are problems with using pH testing for diagnosing Gastroesophageal reflux disease. Despite the fact that normal individuals and patients with Gastroesophageal reflux disease can be separated fairly well on the basis of pH studies, the separation is not perfect. Therefore, some patients with Gastroesophageal reflux disease will have normal amounts of acid reflux and some patients without Gastroesophageal reflux disease will have abnormal amounts of acid reflux.
