Discover if you are suffering
from reflux…

With one simple saliva test, Peptest can help diagnose gastro‑oesophageal reflux from the stomach into the oesophagus, larynx or airways.

Without early diagnosis and treatment, reflux can cause severe damage to the oesophagus and, in some cases, can lead to oesophageal cancer.
