Founded by scientists from the University of California, Los Angeles, PHASE Scientific is a fast-growing biotech startup seeking to empower people with health information. From our roots in the U.S.A., our footprint has expanded globally, with our headquarters in Hong Kong, and manufacturing, R&D, clinical trial, commercialization and other supporting facilities in Southern California, U.S. and Suzhou, China.



We create game-changing technologies that make diagnostic tools easier, faster, more accurate and more affordable.

Combined with the benefits of a health data platform, we enable people to better understand and manage health risks, and take control of their own health.


We believe that everyone should have access to better diagnostic tools and knowledge about their health;

And that better information, in the hands of more people, facilitates better decision-making, empowers action and engenders change:

  • Individuals can make more educated decisions about how they manage their health
  • Healthcare providers can deliver better diagnosis and more effective treatment
  • Researchers can create breakthroughs in science
  • Policy-makers can advance new ways of thinking


Understanding the risk
of tooth decay for better

Tooth decay is the most common oral disease, affecting 2.4 billion people worldwide1.

Our first product, a test kit that offers a fast, inexpensive and easy way to assess the risk of tooth decay, will help patients detect, monitor and prevent this widespread disease.

Increasing detection of
sexually transmitted diseases to slow
their spreading

The world sees hundreds of millions of new cases of sexually transmitted diseases (STDs) each year3. In addition to their impact on quality of life and reproductive health, STDs also indirectly facilitate the sexual transmission of HIV4, which in itself sees 1.8 million new cases a year5. Yet millions of those infected by STDs, including approximately over 11 million people living with HIV/AIDS, are unaware of their status6, and continue to spread the diseases unknowingly.

PHASE Scientific is currently developing STD test kits that will allow anyone to take the tests anywhere at any time. Connected to our health data platform via a mobile app, patients can choose to consult with a healthcare professional remotely, in total privacy. We believe this will encourage more people to find out their status, get treatment, and slow the spreading of the diseases.

and Syphilis

Identifying infected
patients to eradicate

There are over 200 million malaria cases and over 400,000 deaths a year. Children under five years old are particularly susceptible, with malaria taking the life of a child every two minutes8.

PHASE Scientific has received a grant from the Bill & Melinda Gates Foundation to develop a saliva-based test for malaria that delivers fast results without the need for equipment, power or trained technicians. This will help to identify and treat infected patients, particularly in remote or resource-poor areas, and help to control the spreading, and ultimately achieve the elimination, of malaria.
