Peptest. A non-invasive test to diagnose reflux

Publisert på
Doctors and healthcare professionals who have been using the world’s first non-invasive test to diagnose reflux are urging others to do the same.

Peptest, a unique testing kit developed by UK-based RD Biomed, measures a patient’s saliva/sputum for levels of pepsin, an enzyme found only in the stomach. If a patient’s Peptest is positive for pepsin, then it suggests that they are suffering from reflux and it can also be an indicator of other reflux-associated conditions.

Without early diagnosis and treatment reflux can in time lead to severe damage to the oesophagus (erosive oesophagitis) and to a pre-cancerous condition called Barrett’s Oesophagus which in some cases can lead to oesophageal cancer. In certain cases it may also be linked to cancer of the Larynx.

Current reflux detection methods are time-consuming and extremely unpleasant for the patient. For example tests to confirm laryngopharangeal reflux include dual channel 24-hour PH monitoring or multi-channel intraluminal impedance measurement. Both require the patient having a catheter inserted down their nose, into the stomach and taped in place for 24-hours.
