Test-free Zero-contact Point-of-care Universal Screening of Complex Diseases

Early detection of complex diseases remains limited by the need for specialized tests, clinical encounters, and manual interpretation. I will present a new paradigm: test-free, zero-contact, point-of-care universal screening based entirely on longitudinal medical histories. Built on the Zero-burden Comorbidity Risk (ZCoR) framework and its extensions within Large Health Models, this approach infers high-dimensional comorbidity dynamics to forecast diverse conditions—from neurodegeneration to pulmonary fibrosis—years before clinical recognition. Unlike traditional diagnostics, screening requires no questionnaires, imaging, labs, or patient interaction; risk estimates emerge automatically from routine encounter data already present in electronic health records. I will describe the mathematical foundations enabling disease-agnostic forecasting, the construction of hyper-realistic digital twins, and the generation of phantom cohorts for validation. Results across multiple cohorts show population-scale deployability, high predictive accuracy, and transformative implications for proactive, equitable care. This framework redefines screening as a passive, continuous, and universally accessible capability.
