Health signals
from inside your body,
revealed with a single breath
BreathIR makes ultra-precise analysis a reality.
Disease has its own unique odor
Cells breathe, too
The cells in our body take in nutrients, produce energy, and carry out metabolic activity. The gaseous byproducts inevitably released during this process are precisely VOCs (Volatile Organic Compounds).
Abnormal cells give off a different odor
Cancer and disease cells proliferate far more rapidly and behave far more aggressively than normal cells. Just as a factory emits different fumes when it is pushed beyond its limits, disease cells release VOCs of entirely different kinds and proportions than normal cells.
They travel through the blood and are exhaled in the breath
These distinctive VOCs produced by cells circulate through the blood vessels, then mix with the breath in the lungs and are released outside. What dogs detected was not a simple body odor, but this 'chemical signal of a specific metabolic abnormality (Odor Signature)' mixed into the breath.
The dog's remarkable sense of smell
that detected disease before human science could
"Disease has a unique odor"
With a sense of smell more than 10,000 times keener than humans', dogs can detect changes in trace amounts of volatile organic compounds (VOCs) released from our bodies. Their ability to identify disease through the distinctive metabolites produced by cancer cells—that is, an 'Odor Signature'—has been proven in numerous cases.

1989
In the UK, a companion dog persistently bit at a mole on its owner's leg, prompting a visit to the hospital, which led to the discovery of an early-stage malignant melanoma (skin cancer).
-
2009
In the UK, 'Daisy,' the companion dog of Dr. Claire Guest of a cancer detection dog research center, contributed to the early detection of a specific disease-related metabolic signal.

2011
In an experiment by a research team at Kyushu University in Japan, Marine distinguished colorectal cancer patients using only the smell of the patients' exhaled breath and stool. The accuracy was a remarkable 98%.
Now, advanced human science,
BreathIR makes ultra-precise analysis a reality.
The BreathIR system leverages mid-infrared Quantum Cascade Laser (QCL) spectroscopy technology to quantitatively analyze trace gases at the ppb (parts per billion) level that were difficult to measure with conventional sensors.
Mid-Infrared
Quantum Cascade Laser
The QCL (quantum cascade laser) uses laser light of specific wavelengths to selectively and highly precisely measure breath gas components. This minimizes interference from other substances and provides accurate quantitative analysis values, maximizing the reliability of the service.
Breath gas analysis
Breath Gas Analysis for Metabolic Monitoring
The BreathIR system measures the concentrations of four key biomarkers in our breath, providing quantitative monitoring insights based on relevant research data. This is used not as a medical diagnosis, but as scientific reference material for setting the direction of personal health management and for professional consultation.
