Integrate Breath Biopsy® into your COVID-19 Research

Exploring Breath Biomarkers for COVID-19 Research

The 2020 COVID-19 pandemic (also referred to as SARS-CoV-2 or Coronavirus) has had widespread impacts across the world. As an infection that primarily affects the lungs, the application of breath analysis could be an effective tool in managing COVID-19 infection and understanding its wider health impacts.

Owlstone Medical's Breath Biopsy platform provides wide-ranging breath-based biomarker discovery capabilities that are available to address research challenges with relevance to COVID-19. These could include:

  • Capture of viral particles or RNA in respiratory droplets using disposable breath collection devices and analysis using PCR or novel diagnostics. 
  • Non-invasive assessment and monitoring of lung damage resulting from COVID-19 infection using volatile organic compounds and other non-volatile macromolecules, such as inflammatory mediators, in exhaled breath. Discovery workflows may identify biomarkers to help stratify patients and optimise the use of ventilators and specialist care resources in the face of high demand.
  • Investigating the relationship between COVID-19 and pre-existing conditions or environmental factors such as air pollution by measuring exogenous and endogenous volatile compounds on exhaled breath. The Breath Biopsy platform supports broad-ranging biomarker discovery as well as targeted panel analysis making it useful for investigating the impacts of various biological and environmental factors.

Using Biomarkers on Breath for Viral Infections

Beyond the gases in the air, exhaled breath is a rich source of potential biomarkers for use in a wide range of medical and health-related contexts. These can primarily be divided into volatile organic compounds (VOCs) and respiratory droplets. Many VOCs are produced as a result of metabolic processes throughout the body and reach the breath via the bloodstream, they can also originate in the airways or from exogenous sources such as air pollution. Respiratory droplets are produced from fluids within the lungs and airways and can carry proteins, nucleotides or even whole viruses and bacterial cells.
