Symptom screening, reimagined.

In order for a COVID-19 symptom screening procedure to be effective, screening must meet certain criteria at security checkpoints.

Screening must be conducted often, performed rapidly, detect early symptoms accurately,  whilst being cost-effective. 


With Corowell, tests are easy & non-invasive with results obtained in less than 90 seconds. As such, tests can be taken daily – the more people are tested, the higher the probability of detecting an infection, the sooner clusters can be contained.  

Rapid mass testing

Corowell’s screening method is rapid and accessible with a single click to validate a Corowell Pass. It’s suitable for mass-markets and can be performed in seconds on site at the airport for example without additional infrastructure.

Detect early symptoms accurately

The Corowell Symptom test can identify with high accuracy (~85%) real time infected people by diagnosing the COVID-19 caused symptom of Anosmia. Anosmia is considered as one of the earliest COVID-19 symptoms and usually occurring anytime between 1-3 days after infection.


Corowell tests are low-cost compared to PCR, antibody and antigen tests. Furthermore the test can be self-administered and taken anytime and anywhere, at home for example.
