About Us

CO-Check is a brand name under Sanwa BioTech Limited, a company with the core mission to save lives by streamlining clinical diagnostic processes.

CO-Check’s rapid test kits are developed as a series of personalized Point-Of-Care Testing (POCT) solution that provide affordable, reliable and rapid diagnostic results to individuals and front-line healthcare professionals for a faster treatment to time-threatening disease like the COVID-19.


With CO-Check, we empower untrained individuals to conduct tests away from crowds and at the safety of their own homes. This dramatically reduces risk of exposure, while also providing individuals with accurate results with no efforts.
