Exhaled breath is a rich source of prospective clinically-relevant biomarkers. Several are already in widespread use, including oxygen, carbon dioxide, hydrogen, methane, nitric oxide and sulfur compounds, yet many more remain to be discovered. Breath contains over 1,000 VOCs of which many have links to metabolism and disease processes, and some have the potential to become biomarkers for disease detection and precision medicine.

Breath offers many possible advantages in terms of non-invasive collection, ease of use, relevance to a wide range of clinical needs. Yet the complexity of breath and potential for ambient contamination has made reproducible analysis challenging.

Breath Biopsy OMNI is the only commercial biomarker platform optimized for on-breath global VOC analysis. If you’re seeking a method for non-invasive global biomarker research that provides easy, flexible sample collection, high resolution compound analysis and reproducible results that you can trust then talk to us about OMNI.

What are 'on-breath' biomarkers?

Many biomarker research studies report on the number of features detected during analysis, or the number of identified compounds. Breath research studies often report hundreds of compounds in each breath sample, but many of these could originate from external and ambient sources and may have no relevance to a patient’s biology. This adds to the noise in the system and reduces the chance of finding robust biomarkers that will survive validation and could have clinical relevance.

OMNI utilizes a clear definition of on-breath compounds to optimize detection, and has been thoroughly tested to ensure reproducibility in compound detection.

Biomarkers backed by biology

OMNI has demonstrated the capability to repeatably measure up to 500 VOCs from breath including molecules with known associations to a range of metabolic pathways and disease mechanisms. Detected compounds include alcohols, ketones, aldehydes and alkanes and have been linked to conditions including chronic respiratory diseases, liver diseases and inflammation, which are collated in our Breath Biopsy knowledge base.

The sensitivity afforded by HRAM mass spectrometry, Breath Biopsy sample collection and our custom data analysis allows the detection of dozens of very low abundance breath VOCs that have yet to be widely studied and have equal potential as biomarkers.

The detection of the combination of well-known biologically relevant as novel VOCs makes OMNI the most comprehensive platform for VOC biomarker studies.

Breath sample processing

Samples are analysed using Breath Biopsy Services in the world’s only specialist Breath Biopsy Laboratory. We use a custom pipeline built around high-resolution accurate mass (HRAM) gas chromatography mass spectrometry (GC-MS). Our quality assurance process is accredited to ISO-9001 standard to help ensure all samples are processed to the same high level of quality and consistency.

OMNI processing and analysis includes:

  • Capability to detect over 500 breath VOCs and facilitate compound identification and validation
  • Compound detection based on high-resolution accurate mass (HRAM) Orbitrap mass spectrometry, sensitive to ppb levels
  • Compound identification through bespoke Breath Biopsy HRAM Library and generic NIST library matching
  • Access to in-house expertise on study design, clinical trial management, statistical analysis and result interpretation

Reporting and interpretation

We have developed our own HRAM Breath Biopsy Library of over 130 compounds detected on breath using Breath Biopsy. The Library enables high confidence identification of compounds from the results of our GC-MS analysis. All OMNI studies result in a comprehensive feature table including compound IDs obtained through the Breath Biopsy Library or comparison to online NIST data.

Depending on your needs, we can also provide detailed reporting and expert interpretation to support the results of your study. This can include thorough statistical analysis, both uni- and multivariate analysis, designed to address your scientific questions, accompanied with biological and clinical interpretation of observed results based on established knowledge and published scientific literature.
