Challenges: Technical, Clinical, and Adoption Barriers

Exhaled breath analysis technologies have advanced rapidly, yet several significant challenges persist as the sector moves through 2025 and into the coming years. These barriers span technical, clinical, and adoption domains, each influencing the pace and breadth of real-world implementation.

Technical Challenges remain at the forefront. The detection of volatile organic compounds (VOCs) and other biomarkers in exhaled breath requires highly sensitive and selective sensors. Many current devices, including those developed by Owlytics Healthcare and Breathomix, rely on advanced sensor arrays and machine learning algorithms. However, reproducibility and standardization across devices and environments are ongoing concerns. Environmental factors such as humidity, temperature, and background air composition can introduce variability, complicating the interpretation of results. Furthermore, the miniaturization of gas chromatography-mass spectrometry (GC-MS) and the development of portable, cost-effective alternatives remain technical hurdles, as highlighted by ongoing R&D efforts at Siemens Healthineers.

Clinical Barriers are equally pressing. While pilot studies and early clinical trials have demonstrated the potential of breath analysis for disease detection—including lung cancer, asthma, and infectious diseases—large-scale, multi-center validation is still limited. Regulatory approval processes, such as those overseen by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), require robust evidence of clinical utility, sensitivity, and specificity. Companies like Breathomix and Owlytics Healthcare are actively engaged in clinical collaborations, but the translation from promising pilot data to routine clinical use is slow. Additionally, the lack of universally accepted reference standards for breath biomarkers complicates both clinical validation and regulatory review.

Adoption Barriers further temper the outlook. Healthcare providers and payers remain cautious, often citing insufficient evidence for cost-effectiveness and clinical impact. Integration with existing healthcare IT systems and workflows is another challenge, as is ensuring data privacy and security—especially when cloud-based analytics are involved. Patient acceptance, while generally favorable due to the non-invasive nature of breath analysis, can be influenced by concerns over data use and device reliability. Industry groups such as the MedTech Europe are working to address these issues through advocacy and standardization initiatives.

Looking ahead, overcoming these barriers will require coordinated efforts among device manufacturers, clinical researchers, regulatory bodies, and healthcare providers. Progress in sensor technology, standardization, and clinical validation is expected, but widespread adoption will likely depend on demonstrating clear clinical and economic value in real-world settings over the next several years.
