Gastrolyzer® Interpretation Chart Update

Gastrolyzer® Interpretation Chart

Included with every Gastrolyzer® range order, Bedfont® Scientific Limited provides practical resources designed to support and simplify hydrogen and methane breath testing (HMBT). One such resource was the interpretation wheel, which, until December 2025, offered clinicians a quick reference for interpreting Gastrolyzer® results. This resource has now evolved into a clear, A5 interpretation chart.

Why the update?

As part of the Bedfont® commitment to providing accurate, evidence-based clinical guidance, the interpretation resource has been updated to an A5 chart that offers a clear, concise, and practical reference for quick use during testing and reporting.

The new format includes tips for sample collection from ‘The Essential Guide to Hydrogen and Methane Breath Testing.’ A book by Dr Jafar Jafari, Head of Upper GI physiology at Guys & St Thomas’ Hospital, and a member of Bedfont’s Medical Advisory Board.

The new resource also aligns with the North American Consensus on HMBT.

What is the North American Consensus on HMBT1?

The North American Consensus on HMBT is a set of guidelines developed by a panel of North American experts in gastroenterology and breath testing. They address variation in practice and improve consistency, accuracy, and clinical relevance of breath test results.

Previously, breath testing practices varied significantly between clinics, which could lead to:

  • Inconsistent interpretation of results,
  • Confusion over cut-off values,
  • Reduced confidence in clinical decision-making.

The North American Consensus provides clear, agreed definitions and thresholds that help to ensure results are interpreted in line with recognised best practice.

Why clarity matters in interpretation tools.

Bedfont® understands that testing clinics are often under time pressure and that clear, concise, and simple interpretation resources are essential. That’s why its new interpretation resource is being supplied in an easier-to-read A5 chart format.

By aligning with recognised consensus guidance and prioritising clarity, the updated Gastrolyzer® interpretation chart is designed to help healthcare professionals provide confident interpretations promptly.
