Rapid detection

Manufacturer's Description

Check4™ is a highly accurate self-testing platform that is fast, accurate and affordable. It rapidly detects early and asymptomatic infections from saliva with the accuracy of a PCR test, but without reagents, diagnostic machines, technicians and delays.
Tiny sensors by Identifysensors lie at the heart of some of the most sensitive pathogen tests in the world. Clinical tests show these ink-printed sensors detect COVID RNA down to 200 gene copies/ml. That is less than half than sample size used for a standard PCR test, while enabling positive results for very early infections.   

IdentifySensors Biologics and some of the world’s leading researchers at Purdue University have commercialized a new and disruptive electronic technology that rapidly detects multiple pathogens, including influenza, mumps, measles, MRSA, Hep C & B, HIV, foodborne pathogens and more.

The Check4™ platform soon will move medical testing away from antiquated chemistry labs and into consumers’ homes.

Current chemical-reaction tests will be replaced by fast and affordable digital sensors that connect to a smartphone. Consumers will be able to test themselves at home or on the go for multiple infections, with PCR accuracy in minutes. Businesses and organizations will have the ability to remotely monitor employees and customers in real time.

The benefits of accurate, over-the-counter testing include immediate results without a doctor’s visit or prescription; fast, easy access; more frequent testing; earlier detection; lower costs; reduced transmission rates; and improved population health.
