Assay validation and testing

Biomarkers have a central role in patient management.

Geneuity provides numerous tools to detect and characterize biomarkers. Characteristics of a good biomarker assay include target method and analyte performance, specifically sensitivity / prediction, specificity, accuracy, and precision. However, choosing the right biomarker for a clinical study also requires an in-depth knowledge of the disease process that can only be provided by experienced, board certified pathologists and scientists. These specialists provide specimen suitability, clinical utility, interpretation of results, and integration of all pathology data.

Biomarkers support screening, diagnosis, risk stratification, treatment selection, and clinical course monitoring. Geneuity’s capabilities in biomarker assay validation and testing, supported by more than a decade of clinical laboratory experience in personalized medicine, brings a broad mix of technologies, platforms, and capabilities to support drug development.
