We’ll be at a leading conference for otolaryngologists this week to demonstrate how Peptest can be used to differentiate between laryngopharyngeal reflux (LPR) and gastro-oesophageal reflux disease (GORD).

The 15th British Academic Conference in Otolarynology (BACO), which takes place in Liverpool on 8 to 10 July 2015, is a triennial event aimed at ENT/head and neck surgeons, specialist nurses, audiologists and speech and language therapists.

Our research manager Dr Vicki Strugala will present a poster and abstract titled: “Differentiation between LPR and GORD with the use of a simple non­invasive diagnostic test for reflux by detection of pepsin in expectorated saliva”.

Studies have shown that Peptest has the potential to differentiate LPR and GORD, especially if samples are taken at set times and pepsin concentration measured. For example, there is a distinction between GORD and LPR patients as pepsin level is significantly higher first thing in the morning and further increased when symptoms are noted.

Emma Stapleton, an Otolaryngology Specialist Registrar at Doncaster Royal Infirmary, will also present an abstract at BACO that identifies the value of salivary pepsin assay as a diagnostic test for LPR.

The abstract will include data produced by Mr Mark Watson, ENT consultant at Doncaster Royal Infirmary.
