Who we are
Trears Biomarkers is focused on transforming how chronic conditions are detected, monitored, and managed. We develop medical devices and biomarker platforms that capture long-term biological levels, overcoming the limitations of point-in-time blood or saliva testing.
Trears operates at the intersection of clinical science, diagnostics, and digital health, with applications across metabolic syndrome, cardiovascular risk, stress biology, and other chronic disease pathways. Our company is headquartered in London & Chile and collaborates with academic, clinical, and industry partners in the, highly specialised multidisciplinary team
Business HQ: UK and Chile.
Turnover: Pre-revenue (R&D and validation phase II)

Our StoryTrears has been developed through collaborations with clinicians, researchers, and innovation programmes in the UK and internationally.
Relevant experience includes:
• Clinical and scientific validation of novel biomarker approaches [3 peer-review papers]
• Participation in MedTech, Innovate UK, innovation accelerator programmes
• Collaboration with academic and healthcare stakeholders on chronic disease research
• Early engagement with regulators, investors, and healthcare systems regarding adoption pathways
Why Trears?
Trears is differentiated by its unique biomarker matrix and clinical philosophy:
• Proprietary earwax-based biomarker platform enabling long-term biological measurement
• Non-invasive, low-burden sampling designed for repeated and real-world use
• Strong scientific and clinical grounding, including peer-reviewed validation
• Focus on chronic disease monitoring rather than single time-point diagnostics
• Zero reported safety incidents across development and testing phases
• Sustainability-aligned materials and patient-centric device design
Trears does not aim to be a general diagnostics provider; it specialises in long-term physiological insight for chronic conditions, where conventional testing performs poorly.
