DxTerity Diagnostics has declared conformity with the requirements of the European In Vitro Diagnostic Directive and has applied the CE mark to the REDI-Dx Radiation Biodosimetry Test for the quantitative estimation of the absorbed ionising radiation dose after a nuclear event.

A radiological event, from the use of a nuclear weapon or improvised nuclear device, could potentially expose thousands of individuals to high or moderate levels of radiation that would require immediate medical intervention. REDI-Dx measures the biological response to radiation and provides individualised estimates of absorbed radiation from a peripheral blood sample. Physicians can use the estimate, in conjunction with radiation dispersal monitoring and clinical signs and symptoms, to prioritise the highly and moderately exposed individuals from the concerned public for medical treatment.

According to Bob Terbrueggen, CEO and Founder of DxTerity, “REDI-Dx fulfills a critical unmet need for responding to a mass scale nuclear event. It is the first CE-IVD assay for radiation biodosimetry and is designed to integrate into existing clinical testing infrastructure and read-out on the installed base of ABI 3500 Dx CE instruments.”

The dicentric chromosome assay is the current “gold standard” in Europe and Asia; however, the limited testing capacity, lack of standardisation, and 72-hour time to result limits its practicality. REDI-Dx overcomes these limitations with ambient sample shipping, 6-hour assay processing time, and a standardised CE-IVD kit for high throughput testing.

REDI-Dx is the result of a multi-year collaboration between DxTerity, Duke University, the University of Arizona, and Thermo Fisher Scientific; as well as patients and researchers from City of Hope Cancer Center and University of California Los Angeles. This project has been funded in whole or in part with Federal funds from BARDA under Contract No: HHSO100201000001C and Contract No: HHSO100201600034C.

The REDI-Dx Biodosimetry Test is designed to measure a panel of gene expression markers and estimate individualized levels of absorbed ionizing radiation from a blood sample after a nuclear event.

DxTerity provides services and technologies to partner organizations, such as molecular diagnostic test development and end-to-end management of population-scale genomic studies.
