Quadrant Laboratories

Quadrant Laboratories, a subsidiary of Quadrant Biosciences, is a life sciences company focused on the development and implementation of epigenetic diagnostic tests. The company operates a CLIA-certified laboratory in Syracuse, New York, where it processes advanced molecular assays, most notably the Clarifi ASD test for autism spectrum disorder. This non-invasive saliva test utilizes a proprietary functional epigenetic analysis platform to identify RNA biomarkers associated with neurodevelopmental conditions. Beyond autism, the company has expanded its portfolio to include diagnostics for mild traumatic brain injury and Parkinson's disease, as well as large-scale infectious disease surveillance. Quadrant Laboratories gained significant prominence for its high-throughput COVID-19 saliva testing and wastewater monitoring programs during the global pandemic.
