PH Metry

PH monitoring is a test that measures how often and for how long the stomach acid enters the food pipe (oesophagus).

It is a test for diagnosing gastroesophageal reflux disease (GERD) in patients in whom upper GI endoscopy is normal, or in those who have atypical symptoms of GERD (dry cough, throat pain, asthma, hoarseness of voice).
