Our Team

With respect to the COVID-19 testing, it chose us more than we chose it! Our expertise in saliva-based, RNA testing - as part of our mission to develop diagnostic tests for autism and other neurological conditions - serendipitously placed us in a position to help address this global pandemic. We are now involved in three COVID-19 projects!

From Epigenetic Diagnostics to Comprehensive COVID-19 Testing. How Did We Get Here?

Leaders in the Development of Epigenetic Diagnostic Tools

Quadrant Biosciences is a life science company working with universities across the US to develop and commercialize epigenetic diagnostic solutions for autism spectrum disorder, Parkinson’s disease, and mild traumatic brain injury (concussion). Working closely with medical researchers such as SUNY Upstate Medical University and Penn State College of Medicine, we have developed a novel, saliva-based diagnostic platform called Clarifi®.

In December 2019 we launched Clarifi ASD®, the world's first saliva test for autism spectrum disorder. The test, intended for children 18 months through six years of age, provides a probability of an autism diagnosis based on epigenetic markers in the saliva.

Then the COVID-19 pandemic happened.

Not long after we began to introduce Clarifi ASD to pediatric health care providers, the world was besieged by the COVID-19 pandemic. Our ability to access healthcare providers and share the scientific and practical utility Clarifi ASD provides to parents and physicians was greatly restricted by social distancing mandates and virus concerns which, in turn, limited our sales team’s ability to affect sales and increased commercial demand for Clarifi ASD. As a result, our sales of the Clarifi ASD test have been below expectations.

So, we adapted!

In response to the COVID pandemic, we immediately reduced our operating costs and, given our existing experience with RNA analysis - and the fact that COVID-19 is an RNA virus - we made the decision to pivot and work with our university partners to develop diagnostic tools for COVID-19. As a result, today we are involved in three significant, complementary COVID-19 projects to aid in the detection of COVID-19 in individuals and communities across the U.S.

Watch this brief overview video of our company projects:

Three Levels of Testing: A Comprehensive Approach to Assessing COVID-19

1. Individual Testing - Clarifi COVID-19 Test Kit

The development of an individual saliva test for COVID-19 was a natural extension of our earlier work with Clarifi ASD®, which used a similar saliva collection methodology. Working in partnership with SUNY Upstate Medical University, we developed the "Clarifi COVID-19 Test Kit by SUNY Upstate Medical and Quadrant Biosciences," a non-invasive and easy to administer swab that collects saliva which is then analyzed to determine the presence or absence of the SARS-CoV-2 virus. On September 22nd, we received Emergency Use Authorization (EUA) for the Clarifi COVID-19 Test Kit!

The Clarifi COVID-19 Test Kit contains the saliva collection swab and the reagents needed to run the analysis and is available for use by high-complexity clinical laboratories serving patients through physicians' offices, urgent care clinics, and hospitals.

2. Community/Municipal Screening: Wastewater Surveillance

This project, funded by New York State, involves our collaboration with SUNY ESF, Upstate Medical University, Syracuse University, and global civil engineering firm Arcadis, to collect and analyze wastewater from the county and municipal sewer systems for the presence of the COVID-19 virus. Our analysis of wastewater samples provides local health officials and policymakers with early indications and information regarding the presence and preponderance of COVID-19 infections in these communities.


“This can be a real game-changer in the detection and monitoring of COVID-19. Information from this testing will allow municipalities to estimate COVID-19 transmission in real time, provide instant feedback on social distancing and reopening phases, help predict hospitalizations and provide confidence for locations with zero transmission to resume normal activity.”

Richard Uhlig, Founder and CEO of Quadrant Biosciences

Because this allows for large regions to be effectively tested for the presence of the COVID-19 virus, it provides a cost-effective and efficient way to screen residents in towns, cities, states, and universities, even in the absence of individual testing.

3. Group/College Testing: Pooled Testing

Finally, in response to an overwhelming need to efficiently test university students prior to attending classes, we have partnered with the Upstate Medical University to conduct pooled testing services for over 450,000 students preparing to begin the fall semester at SUNY schools.

Each of these pooled tests for COVID-19 involves a single test of saliva samples collected from a group of 12 students. A negative test result means that all 12 students are presumed to be coronavirus-free. A positive test for the pool would mean every student in that group would need to be individually tested. Performing single tests of groups of students greatly reduces the cost of supplies, staffing, and time required to perform and interpret tests.

"SUNY Upstate Medical University's work with Quadrant Biosciences, a Start-Up New York company, has led to important breakthroughs in the development of saliva-based diagnostic solutions for neurological conditions such as autism spectrum disorder, Parkinson's disease and concussion injuries. The ability to transfer this innovative approach to assist colleges and universities with the unprecedented and complex work of preparing for the return of students to campuses across the state is an important part of New York's response to the COVID pandemic."

Dr Mantosh Dewan, Interim President, SUNY Upstate Medical University


*On September 22, 2020, The Clarifi COVID-19 Test Kit obtained Emergency User Authorization (EUA) by the Food and Drug Administration (FDA) to be used for the diagnosis fo SARS-CoV-2. The Clarifi COVID-19 test Letter of Authorization, along with the authorization Fact Sheet for Healthcare Providers, the authorized Fact Sheet for Patients and authorized labeling are available on the FDA website.

The Clarifi COVID-19 Test Kit has not been FDA cleared or approved. It has been authorized by the FDA under an emergency use authorization for use by authorized laboratories. Clarifi COVID-19 has been authorized only for the detection of nucleic acid from SARS-CoV-2, not for any other viruses or pathogens, and is only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of in vitro diagnostic tests for detection and/or diagnosis of COVID-19 under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner.

Despite the fact that we have the expertise, capability, and customer demand for these COVID-19 tests, the supplies needed to perform quantitative PCR are becoming increasingly difficult to obtain. This, and supply chain disruptions generally throughout the industry, could impair our ability to successfully commercialize one or all of these tests.

But, we are still very much an Epigenetics Diagnostic Company!

The Clarifi ASD® Test - A Game-Changer for Autism Diagnostics

We continue to maintain a focus on our core mission to develop epigenetic diagnostic tools, such as Clarifi ASD®, the world's first saliva test for autism spectrum disorder.

What is it?

Clarifi ASD is a saliva test that indicates the probability that a child has autism spectrum disorder.

Who is it for?

Clarifi ASD is being used primarily by pediatricians and family physicians with patients (18 months through 6 years of age) with a positive autism screening test or a clinical suspicion to aid in a formal diagnosis.

Why is it needed?

With 1 in 54 children being diagnosed with autism in the US according to the CDC, it is one of the most commonly diagnosed developmental disabilities in the country. Unfortunately, the current diagnostic process involves long wait times, largely the result of a small number of trained clinicians to administer behavioral tests. This, in turn, leads to delays in children receiving critical intervention services. If autism is identified and treatment is initiated early, the trajectory of a child's life can be positively changed.

How Clarifi ASD Can Make a Difference

For the first time, clinicians have an accurate biological tool to aid in the early diagnosis of autism. With this simple saliva test, Clarifi ASD can:

~ Help start services earlier when treatment is most effective

~ Provide specialists biological data to support their behavioral assessments

~ Facilitate cost savings through improving the diagnostic process

"What we’ve been able to do over the last 7 years, working together with a very dedicated team, is develop a test that utilizes saliva and can accurately distinguish whether a child has autism spectrum disorder or does not. This relies on a new type of molecular analysis that wasn't even possible until recently."

Frank Middleton, Ph.D. Associate Professor of Neuroscience and Physiology, Biochemistry and Molecular Biology, Pediatrics, and Psychiatry and Behavioral Sciences.

When was it launched?

Clarifi ASD was launched commercially in the US in 49 states (excluding New York), in December 2019.
