Chronic cough, hoarseness, or throat discomfort may not just be a simple irritation—they could be caused by acid reflux. Because these symptoms can stem from various conditions, specialized testing is essential to determine if reflux is a contributing factor.
At SoCal ENT, we utilize Restech’s Dx-pH System, a cutting-edge diagnostic tool that detects both liquid and aerosolized reflux, providing a comprehensive analysis of your airflow and acid levels.
Our expert ENT specialists offer precise, minimally invasive acid reflux testing in a comfortable, patient-focused environment. By accurately diagnosing reflux-related symptoms, we can develop a targeted treatment plan tailored to your needs.





Acid reflux testing is a diagnostic procedure that measures acid levels in the throat to determine if reflux is causing persistent symptoms.
Unlike traditional methods that only detect liquid acid, Restech’s Dx-pH System also identifies aerosolized reflux, providing a more complete picture of reflux activity. Our testing methods help determine the severity of your reflux and guide the most effective treatment plan.
On the day of the procedure, a clinician inserts a small probe through the nose to the back of the throat. The probe is then secured to your cheek and wrapped behind your ear to keep it in place. You will wear the probe for 24 hours while going about your normal activities, including eating, drinking, and talking.
During the test, you’ll use a wireless recorder to log key moments such as symptom onset, meals, and sleep periods. This real-time tracking helps correlate your symptoms with reflux activity, providing valuable insight for diagnosis.
At the end of the test, the probe is gently removed, and your data is analyzed. Your doctor will then discuss your results and personalized treatment plan at a follow-up appointment.
