The proton pump inhibitor (PPI) test in GERD: does it still have a role?
The proton pump inhibitor (PPI) test is a short course of high-dose PPI, used to diagnose gastroesophageal reflux disease (GERD). This diagnostic strategy is commonly used globally, primarily because of its availability, simplicity, and high sensitivity. The PPI test has been proven to be a sensitive tool for diagnosing GERD in noncardiac chest pain patients and in preliminary trials in extraesophageal manifestations of GERD. Several recent meta-analyses reevaluated the value of the PPI test in patients with classic GERD-related symptoms and noncardiac chest pain. Although the results were conflicting, the PPI test remains a popular tool for determining the presence of GERD. Attempts to challenge the PPI test without offering attractive alternatives are unlikely to alter clinical practice.
