Devyser Diagnostics AB (publ) announced an article titled "Detection of donor- derived cell-free DNA (dd-cfDNA) in the setting of multiple kidney transplantations" was published in the journal, Frontiers in Immunology. This study was done in collaboration with the Departments of Immunology and Nephrology at the University of Zurich, including Dr. Jakob Nilsson using the One Lambda Devyser Accept cfDNA assay. This is the first report on the use of an NGS assay to detect dd-cfDNA from multiple kidney transplants to monitor organ damage following transplantation.

dd-cfDNA is used as a marker for monitoring organ damage and rejection following transplantation. Successfully differentiating dd-cfDNA in patients who have received a dual donor kidney transplant, or a sequential transplant, is a significant challenge in the accurate monitoring of such patients. This study showed that transplant patients had detectable cfDNA from multiple donor grafts and One Lambda Devyser Accept cfDNA was able to maintain a high sensitivity.

The authors concluded that the results have the potential to influence clinical decision-making.
