What is Oral Salivary Pepsin Testing?
Oral Salivary Pepsin Testing (or Peptest®) is a new non-invasive method to determine whether you have laryngopharyngeal reflux. It is a non-invasive diagnostic test that involves collecting saliva samples at certain time points during the day. You will be provided with 3 specialised tubes and clear instructions on when and how to collect these samples.
The test looks for the absence or presence of pepsin, a digestive enzyme which is only produced in the stomach. If pepsin is detected in your saliva, then an element of laryngo-pharyngeal reflux must be present, and may explain some or all or your symptoms. Furthermore, the Peptest® can quantitatively test the actual levels of pepsin in your saliva, giving us a measure of the severity of your LPR.
This test is available to be ordered via post or collected from our rooms as soon as possible after you have completed your samples, you will be required to post or drop them off in person to our rooms (within a few days ordinarily).
You will be provided with a detailed information sheet and instructions on how to collect the samples. A full diagnostic report will be provided to yourself and your GP after your saliva samples have been analysed.
