History

RD Biomed is a United Kingdom-based company specializing in healthcare product development with a focus on gastroenterology. It is headquartered in Hull, according to Wikidata, which describes it as a UK manufacturer of in-vitro diagnostic medical devices for reflux diagnosis. The company was founded by Professor Peter Dettmar, who serves as a director and is described on the company's website as the author or co-author of more than 530 journal papers, abstracts, and book chapters on gastro-intestinal matters. The company's flagship product, Peptest, is an immunological in-vitro diagnostic medical device that rapidly detects the gastric enzyme pepsin in saliva, sputum, and exhaled breath condensate samples. The presence of pepsin in these samples is an indicator of gastro-oesophageal reflux disease (GORD), which affects 20–30% of adults, or laryngopharyngeal reflux (LPR), often referred to as "silent reflux." Peptest is positioned as a non-invasive alternative to more costly and invasive procedures such as endoscopy; a testimonial on the company's website notes that Peptest's simplicity means patients do not have to be referred to secondary care, avoiding the expense of referral and endoscope procedures. RD Biomed's activities extend beyond diagnostics to include pharmaceutical development and clinical trials. The company states that its products have been routinely used with patients in global gastroenterology, ENT, chest, and respiratory clinics, and have wide use in paediatrics. It has achieved ISO 13485:2016 certification, the internationally agreed standard specific to the medical devices industry. The company markets its products worldwide and operates as a private entity.
