A chronic cough or hoarseness might actually be caused by reflux. Because these symptoms can have many causes, a pH test can confirm if reflux is a likely contributing factor to your symptoms and provide details on how severe it is. The unique sensor used in Restech’s Dx-pH System can detect the pH of both liquid and aerosolized reflux, offering a comprehensive analysis. At LAENT, we strive to deliver the best Acid Reflux Testing Los Angeles has to offer.
