Precision medicine's promise remains unfulfilled due to inadequate diagnostics development. The fragmented ecosystem hinders collaboration between academia, pharma, and diagnostics, leading to inefficient assay transfers and limited scaling. A holistic, collaborative approach is needed to integrate biomarker validation, global deployment, and clinical adoption, addressing challenges in intellectual property, data sharing, and risk-gain balance. This unified effort aims to accelerate diagnostics innovation and realize precision medicine's potential.
