Diagnosis of gastroesophageal acid reflux gerd


There is no standard criterion for the diagnosis of GERD. Heartburn and regurgitation, with or without dysphagia, comprise the clinical syndrome of GERD and are the basis for making a clinical diagnosis. In a study by Klauser et al. , symptoms of heartburn and acid regurgitation were reported to have a high specificity (more than 90%) for GERD, but a low sensitivity. It is also well accepted that some patients can present with atypical symptoms, which are listed in. As such, making an accurate diagnosis of GERD on the basis of a subjective evaluation of symptoms alone is extremely challenging. (Dent J, 2007)
