Domus Diagnostics Moves Closer to Delivering Affordable At-Home Molecular Test for COVID-19, Flu-A, Flu-B and RSV

$2.4M contract from the National Institutes of Health (NIH) Rapid Acceleration of Diagnostics (RADx®) Tech program supports clinical testing of ultra-low-cost remote/at-home diagnostic test

PARK CITY, Utah--()--Domus Diagnostics, a U.S.-based point-of-care diagnostics company, has received an award from the National Institutes of Health (NIH) to further develop its point-of-care nucleic acid amplification and detection test for simultaneous identification of COVID-19, Flu-A, Flu-B, and RSV. The award, up to $2.4M through the NIH’s Rapid Acceleration of Diagnostics (RADx®) Tech program, will support accelerated validation and scaling of Domus Diagnostics' testing platform for clinical trial readiness.

The Domus Diagnostics' platform is an ultra-low cost, zero-power testing platform that will produce novel devices that enable user-friendly, accurate, and effective infectious disease testing at home, in doctors’ offices, or in community testing facilities. The devices will provide a significantly more affordable and accessible global option for infectious disease testing.

“Our mission has always been to develop a lower-cost, accessible and highly accurate testing solution to dramatically expand use and improve outcomes around the world,” said Paul Chapman, president and CEO of Domus Diagnostics. “The NIH award will enable us to take a major next step toward validating our platform and moving into clinical trials.”

Domus Diagnostics is developing a high-performance nucleic acid amplification and detection test that can be manufactured anywhere and sold at a price lower than antigen tests currently sold in the U.S. Unlike an antigen test, however, the Domus test uses advanced nucleic acid amplification chemistry, so it’s not only as easy to use, it also offers higher sensitivity and a more accurate result.

With the Domus test, a clinician or patient simply swabs each nostril, inserts a collection chamber into a card, and after approximately 30 minutes they can view the result. The Domus technology doesn’t require any instrumentation, electricity, or even batteries to run – making it a zero-power testing solution.

"While our tests have been developed based on proven, decades-old science, Domus Diagnostics’ approach is unique in our innovations in both chemistry and device manufacturing," said Dr. Xin Song, scientific co-founder and designated chief scientific officer of Domus Diagnostics. "The innovative components of the Domus molecular test, including our one-pot stabilized reaction beads and the breakthrough invention of a temperature-regulated chemical heater, enable a much simpler user experience and better performance with multiplexing capability on a truly low-cost platform."

Development of the Domus Diagnostic technology has been funded in part with federal funds from the National Institute of Biomedical Imaging (NIBIB), National Institutes of Health, Department of Health and Human Services, under Contract No. 75N92023D00001.

About Domus Diagnostics

Domus Diagnostics is reimagining remote and at-home testing, creating a world where everyone has access to the healthcare they need and where governments and public health organizations globally have the tools to address large-scale infectious diseases head-on. Originally spun out of Duke University in early 2021 by Professor John Reif (Non-Executive Director), Dr. Harald Casebourne Stock (Executive Chair, Board of Directors), and Dr. Xin Song (Chief Scientific Officer - designate), the company is now co-located in Utah and Massachusetts, with a product testing lab at at the Research Triangle Park in North Carolina. Domus aims to change how infectious disease testing is done worldwide, with tests that are affordable, user-friendly, accurate, and rapid enough to address current and future public health outbreaks and crises.
