Introducing Peptest
RD Biomed’s flagship product is our diagnostic device Peptest – an immunological in-vitro diagnostic medical device that can rapidly detect the gastric enzyme pepsin in saliva/sputum and exhaled breath condensate samples.
The presence of pepsin in saliva or exhaled breath is an indicator of gastro-oesophageal reflux disease (GORD) which affects 20-30% of all adults or Larygopharyngeal Reflux (LPR) which is often referred to as “silent reflux”
Worldwide success
RD Biomed’s products have been routinely used with patients in global gastroenterology, ENT, chest and respiratory clinics and have a wide use in paediatrics.
Renowned Expertise
RD Biomed founder and director Professor Peter Dettmar is the author or co-author of more than 530 journal papers, abstracts and book chapters on gastro-intestinal matters.
