PreDxion Bio is a precision medicine diagnostics company focused on developing rapid, scalable diagnostic solutions, notably a saliva-based antigen test for SARS-CoV-2 that can detect the virus in asymptomatic and presymptomatic individuals. Their technology leverages semiconductor fabrication processes to enable testing at a scale of tens of millions per day, addressing critical public health needs for rapid detection and contact tracing. Beyond COVID-19, PreDxion Bio’s core platform originated in critical care, designed for near real-time cytokine and biomarker monitoring to guide immune response management in critically ill patients, including those undergoing CAR-T therapy. This positions them at the intersection of infectious disease diagnostics and precision medicine for immune monitoring, serving healthcare providers and public health officials with actionable, rapid insights[1][2][4].
Founded in 2017 by Caroline Landau, Walker McHugh, and Timothy Cornell, PreDxion Bio emerged from technology spun out of the University of Michigan focused on immune biomarker detection. Early traction included receiving FDA Breakthrough Device designation and partnerships with leading pharmaceutical companies to monitor immune responses and predict adverse events in immunotherapy patients. The company’s leadership includes experienced healthcare and AI experts, such as CEO B. Dusty Majumdar, who brings extensive background in precision healthcare, oncology, and AI-driven diagnostics, and Joe Camaratta, an expert in medical technology commercialization[1][3][6].
