Would you give one breath if you could detect lung cancer and other diseases?

Introducing OneBreath™

A unique technology platform developed by Breath Diagnostics to quantitatively analyze organic compounds in a single breath to detect lung cancer and other diseases.1

Our highly portable system will be readily available to patients through medical providers.1

In contrast to a Low-Dose CT Scan, OneBreath is a quicker and easier way of lung cancer diagnosis. We are currently enrolling patients for our 2nd generation system Pilot Study.

Breath Collection

Patients provide one complete breath via a unique collection system in less than 30 seconds.

Breath Processing and Analysis

In a simple automated process, the OneBreath™ micro-reactor captures the organic compounds contained in the breath. Once captured, the samples is analyzed in our laboratories.

Get Results

Results will be available within 3-4 business days.

Why OneBreath™?

OneBreath™ provides a safe, convenient, and inexpensive way to identify lung cancer in at risk patients, before they know they have a problem.1

Accurate Results

OneBreath™ detects lung cancer with fewer false positives and higher specificity than a low-dose CT scan.


The OneBreath™ system increases access to potentially life-saving lung cancer screenings by being portable enough for use in a physician's office or local pharmacy.


The OneBreath™ technology platform demonstrates a lower false positive rate versus CT scans, reducing the number of unnecessary follow-up diagnostic procedures.

Easy to Use

The simplicity of the OneBreath™ system provides the potential to enhance screening compliance due to the fact that only a single breath is required.
