TVD-2 Breathalyser

Products • Infectious Disease Diagnostics

The TVD-2 provides non-invasive, accurate testing of COVID-19 and other viruses in under 3 minutes.

Key Features

Non-invasive breath testing for infectivity.

Portable, fast and reliable the TVD-2 Breathalyser allows for mass, on-the-spot virus checking.

Fast results

With a single one-minute breath and two-minute test time, results are available immediately to help monitor virus spreading.

Reproducible

Unlike intrusive testing, breath testing enables an efficient collection of virus particles from a person’s lungs, to determine whether they are infectious or not.

Non-invasive

As simple as taking a breath, the TVD-2 Breathalyser can be comfortably used by children, the infirm and the elderly.

Easy and portable

Highly portable and easy to use without technical skills or knowledge allows for easy mass deployment in crowd specific situations.

About TVD-2 Breathalyser

Merging GreyScan’s existing Capillary Zone Electrophoresis (CZE) technology with existing methods of lung disease analysis gives the TVD-2 Breathalyser the advantage of speed, comfort and accuracy when it comes to testing for the COVID-19 causing virus SARS-CoV-2.

Current tests based on polymerase chain reaction (PCR), mmunoassay or antibodies are unable to differentiate live virus particles from non-contagious dead particles and are prone to false positives. Additionally, the invasive nature of testing and slow results times provide barriers to people voluntarily testing.

Acting as a huge sampling surface the lungs provide the greatest method of assessment of infection. Using a similar method as an alcohol breath test the TVD-2 Breathalyser takes a single continuous breath and produces an accurate result within three minutes.

Portable and easy to use the TVD-2 Breathalyser is the only on-the-ground test to provide quick, comfortable and acurate results to help ensure the safety of the broader community whether deployed in crowd situations, at border crossings or in heavily trafficked areas.
