Advice on using Peptest
All you need to know about our reflux diagnostic test…
PEPSIN IS A STOMACH ENZYME
Pepsin should only be in the stomach – if it is found in your saliva, then it means you have refluxed contents from your stomach. We use monoclonal human pepsin antibodies to detect the presence of pepsin in saliva.
We provide customers with tubes to collect saliva samples. We recommend storing them in the fridge.
The tubes contain citric acid, which acts as a preservative, so you can send samples back to our laboratory for analysis.
Peptest is available to most international countries.
If you live outside the UK, we will send your kit using FedEx international priority. We also send you a FedEx return pack with pre-printed airway bill so that your return will be just as quick.
It takes around 20 minutes to analyse your saliva samples in the Peptest laboratory.
We will share results with you on the same day as testing your sample – typically this is within 24 hours of a sample arriving at the lab.
We’ll also send you documentation about your results that you can share with your doctor to tailor the treatment and management of your reflux symptoms.
Peptest and your medication
We recommend that you stop taking antacids and raft-forming/ alginate suspensions such as Gaviscon for 48 hours prior to collecting samples for Peptest analysis.
However, you do not have to stop PPI (Esomeprazole) or H2 receptor antagonist therapy (Ranitidine) as Peptest will still detect pepsin in the presence of these if pepsin is being refluxed.
