Arrow Dx is combining Nanotechnology and Artificial Intelligence (AI) to create an inexpensive, sensitive test to screen early for non-alcoholic fatty liver disease (NAFLD). Our aim is to provide physicians with an alternative to liver biopsy which detects the disease too late. We are working to solve the lack of rapid, reliable, point-of-care, and inexpensive diagnostic devices by bring faster, inexpensive and mobile testing for many other applications that require a rapid response (e.g., epidemic/pandemics, public health crisis, early diagnosis for rising complex non-communicable diseases, testing in emergency rooms). Our technology makes it more affordable for smaller healthcare providers such as Physician Office Labs (~100,000 in the U.S.), independent physicians and public health workers to access diagnostics due to our significantly lower cost as well as our portable, small compact size. Finally, we are also working to create a test for COVID-19 as well as other viruses, initially quantifying the virus in wastewater to help public health authorities and later to detect it in biological samples from individuals and patients.
