Andrew Woodcock, our Chief Scientific Officer at RD Biomed, sat down with Biohit Healthcare to discuss our diagnostic tool, Peptest, and also shared insights from medical professionals who use it with their patients.

Biohit Healthcare, headquartered in Helsinki, specialises in developing, manufacturing as well as distributing kits and assays for screening, diagnosing and monitoring digestive diseases.

As one of our distributors for Peptest, Biohit Healthcare is also an essential partner in making this tool available worldwide.

In the blog, Woodcock discusses several key topics:
  • How Peptest works: He explains the non-invasive testing method using saliva samples to detect the presence of pepsin, an enzyme indicative of reflux.
  • Best practices for sampling: Woody outlines the recommended procedure for collecting saliva samples to ensure accurate results, including the timing and frequency of sample collection.
  • Comparison to traditional methods: He highlights how Peptest offers a simpler, more comfortable, and cost-effective alternative to traditional diagnostic methods like endoscopy and 24-hour pH monitoring.
  • Customer feedback: Medical professionals, including ENT specialists and speech language therapists, find Peptest to be a valuable tool for diagnosing or ruling out reflux quickly and accurately.

“We always recommend that three samples are collected at specific time periods within 48 hours, and clinicians tend to follow the continuous diagnostic plan for silent reflux patients. The continuous diagnostic guideline is for those that experience ongoing symptoms generally not associated with reflux, such as a sore throat, lump in their throat or vocal changes.”
