Clinical Applications: From Oncology to Infectious Disease

Exhaled breath biomarker analysis is rapidly moving from research settings to clinical applications, with 2025 poised to be a pivotal year for the technology. The non-invasive nature of breath analysis, coupled with advances in sensor technology and data analytics, is facilitating its adoption across a range of medical specialties, including oncology, infectious diseases, and respiratory medicine.

One of the most promising clinical applications is in oncology, where exhaled volatile organic compounds (VOCs) serve as potential biomarkers for early cancer detection. For instance, Owkin is collaborating on AI-driven analysis of breath samples for cancer diagnostics. Similarly, Breathomix has developed the SpiroNose system, which is being evaluated in clinical settings for the detection and differentiation of lung cancer and other respiratory diseases.

In infectious disease, the COVID-19 pandemic accelerated interest in rapid, non-invasive diagnostics. Companies such as Telesair and Breathomix are actively developing breath analysis platforms for the identification of viral and bacterial infections. Notably, Breathomix has participated in multicenter studies examining the utility of breath VOCs in distinguishing COVID-19 from other respiratory infections in real-time clinical settings.

Beyond oncology and infectious disease, breath biomarker analysis is being explored for chronic conditions such as asthma and chronic obstructive pulmonary disease (COPD). Owkin and Breathomix are also investigating breath profiling for the stratification of asthma phenotypes and monitoring of disease exacerbations, which could enable more personalized treatment regimens.

Looking ahead, the next few years are expected to bring further clinical validation and regulatory approvals. The integration of breath analysis devices into routine clinical workflows remains a key focus for manufacturers, who are working closely with healthcare providers and regulatory agencies to ensure robust data, reliability, and ease of use. With ongoing advances in miniaturized sensors, cloud-based analytics, and artificial intelligence, breath biomarker analysis is set to become an integral component of precision medicine, supporting earlier diagnoses, real-time disease monitoring, and more targeted interventions across diverse patient populations.

Regulatory Landscape & Reimbursement Trends

The regulatory landscape for exhaled breath biomarker analysis is evolving rapidly as the field matures and more devices approach clinical and commercial deployment. As of 2025, regulatory agencies in the US, EU, and Asia-Pacific are actively shaping the approval pathways for these non-invasive diagnostic platforms. The US Food and Drug Administration (FDA) has begun to clear breath analysis devices through the De Novo and 510(k) pathways, with recent examples including the InspectIR COVID-19 Breathalyzer for SARS-CoV-2 detection. This approval set an important precedent for breath-based diagnostics, highlighting the need for robust clinical validation and the potential for rapid point-of-care deployment.

The European Union’s Medical Device Regulation (MDR) presents both opportunities and challenges for breath biomarker developers. The transition to MDR has raised the bar for clinical evidence and post-market surveillance, but also provides a harmonized regulatory framework. Companies such as Owkin and Breathomix are navigating this environment by collaborating with regulatory bodies and participating in large-scale clinical studies to support CE marking of their devices. Breathomix, for example, is advancing its BreathBase® platform for multiple disease indications, reflecting a broader trend toward multiplexed biomarker analysis and integrated digital health solutions.

Reimbursement remains a key hurdle to widespread adoption. Payers are demanding clear evidence of clinical utility, cost-effectiveness, and improved patient outcomes compared to standard diagnostic approaches. In the US, new CPT codes for breath-based tests are under consideration, and the Centers for Medicare & Medicaid Services (CMS) has begun pilot programs to evaluate reimbursement models for digital and point-of-care diagnostics. In Europe, some national health systems are piloting reimbursement for breath analysis in specific applications, particularly in oncology and infectious diseases, but broad coverage is still limited.

Looking ahead to the next few years, the outlook is cautiously optimistic. Continued regulatory clarity is expected as more devices seek authorization, and multi-stakeholder initiatives are underway to standardize validation protocols and data interoperability. Industry consortia, such as those coordinated by European Lung Foundation, are helping to define best practices and facilitate dialogue between innovators, regulators, and payers. As clinical data accumulates and real-world utility is demonstrated, reimbursement pathways are likely to expand, especially for high-burden diseases where exhaled breath analysis can fill critical diagnostic gaps.

Challenges: Technical Barriers and Standardization

Exhaled breath biomarker analysis has emerged as a promising non-invasive diagnostic and monitoring tool, yet the field faces significant technical barriers and standardization challenges as of 2025. The identification and quantification of volatile organic compounds (VOCs) and other biomarkers in exhaled breath is complicated by their often low concentrations, variability due to individual metabolism, and potential contamination from environmental sources. Sensitivity and selectivity of detection platforms—such as gas chromatography-mass spectrometry (GC-MS), selected ion flow tube mass spectrometry (SIFT-MS), and electronic nose (e-nose) technologies—remain central issues. Despite advances in miniaturization and real-time analysis, such as Owkin’s AI-driven breathomics approaches or Owlstone Medical’s Breath Biopsy® platform, achieving robust, reproducible results across diverse clinical settings still proves difficult.

Sample collection procedures represent another hurdle. Variability in breath sampling—ranging from differences in lung depth, breathing patterns, and collection device design—can impact results. Initiatives by organizations like Owlstone Medical to develop standardized collection kits and protocols are helping address this, but universal standards remain elusive. Furthermore, integration of breath analysis with electronic health records and broader digital health platforms requires harmonization of data formats and interoperability, which is not yet widespread.

Analytical standardization is a prominent concern. There is currently a lack of universally accepted reference materials, calibration standards, and validated operating procedures for breath biomarker detection. This complicates the comparison of results across studies and between different analysis platforms. Consortia such as the European Respiratory Society have issued technical recommendations for exhaled breath analysis, but these are not yet globally unified or universally adopted. Clinical validation and regulatory acceptance are further hampered by this heterogeneity.

Looking ahead, industry stakeholders are increasingly collaborating to establish standardized methodologies, as seen in multi-center trials and cross-industry partnerships. Companies like Breathomix are participating in efforts to harmonize breath collection and analysis protocols. Progress is also anticipated from regulatory engagement: as breath biomarker applications move closer to clinical adoption, agencies such as the FDA are expected to release more detailed guidance specific to breath analysis devices within the next few years. The successful resolution of these technical and standardization barriers is pivotal for the widespread adoption and clinical impact of exhaled breath biomarker technologies.
