*Medical Devices Listing HKMD No.170284

  • Restech is the first and only medical sensor able to measure and chart real-time, continuous pH in both liquid and aerosolized states, revealing reflux-related etiology of presenting symptoms.
  • By using the advanced Restech pH sensor probe, no anesthesia is needed. Eating, drinking and routine activities can be done as usual during the test.
  • The pH sensor probe will be put into the throat through the nose by doctor.
  • The sensor monitors pH value of any liquid or vapor at the throat and the frequency, severity and duration of gastric reflux at the throat for 24 hours.
  • For further enquiries about this test or test booking, please call (852) 2402-2188

More Information about Laryngopharyngeal Reflux

 

What is laryngopharyngeal reflux (LPR)?

b4eeb986ceee270dd685665432018dc4

Laryngopharyngeal reflux refers to the flow of stomach contents (gastric contents) beyond the muscle ring of the top of the digestive tract (upper oesophageal sphincter) and to the back of the throat and the nasal airway (larynopharynx), causing mucosa inflammation and thus various types of respiratory symptoms. Some people may have sound hoarseness, chronic cough and throat clearing etc. The reflux occurs more often when awake than sleeping.
