Explore accurate and gentle acid reflux testing with our dedicated ENT specialists, all within a patient-centered environment.

















If you’re struggling with chronic cough, hoarseness, or throat irritation, the cause might be more than a simple infection, it could be acid reflux. Because these symptoms can overlap with other conditions, specialized testing is often necessary to determine whether reflux is a factor.
At the Southern California Center for Ear, Nose, Throat, and Allergy, our Palmdale specialists use Restech’s Dx-pH System, an advanced diagnostic tool that identifies both liquid and aerosolized reflux. This technology provides a comprehensive picture of reflux activity in the upper airway and throat.
Our experienced ENT physicians perform this testing in a comfortable, outpatient setting, using a precise, minimally invasive approach. By confirming whether reflux is responsible for your symptoms, we can create a targeted, effective treatment plan to help you feel better faster.





Acid reflux testing is a diagnostic procedure that measures the presence and severity of acid exposure in your throat and airway. This helps determine if reflux is the source of symptoms such as chronic cough, hoarseness, or frequent throat clearing.
Unlike older testing methods that detect only liquid acid, the Restech Dx-pH System can measure aerosolized (vaporized) acid, which often goes unnoticed yet contributes significantly to irritation and discomfort. With this information, your provider can design a treatment plan tailored to your unique reflux pattern.
The procedure is simple and completed during a standard office visit at our Palmdale location. A clinician gently inserts a thin probe through your nose to the back of your throat. The probe is then secured to your cheek and wrapped behind your ear to hold it in place comfortably.
After the monitoring period, the probe is carefully removed, and your data is analyzed in detail. Your provider will review the results with you and outline a customized treatment plan during your follow-up appointment.
Experiencing frequent heartburn or acid reflux can be frustrating. Seeking a professional evaluation is crucial to uncover the root cause and explore effective treatment options. By addressing these symptoms promptly, you improve daily comfort and help prevent potential complications from untreated acid reflux.
If you notice irritation, burning sensations not linked to spicy foods, or difficulty swallowing, it might be time for a deeper look. Our specialists begin with a comprehensive assessment of your symptoms and medical history to see if acid reflux testing is the right step for you. This personalized approach ensures you're on the best path to understanding and addressing your concerns.

Acid reflux testing provides a precise, minimally invasive way to understand what’s causing your symptoms and how severe the problem is. The Restech Dx-pH System offers greater diagnostic accuracy by measuring both liquid and aerosolized acid, which can otherwise go undetected.
