CareDx Presents New Data at the American Society for Histocompatibility and Immunogenetics Annual Meeting

Demonstrates Breadth of Offerings for HLA Laboratories and Validation of AlloSeq HCT

CareDx, Inc. (Nasdaq: CDNA) – The Transplant Company™ focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions for transplant patients and caregivers – today announced a leading presence at the 49th annual meeting of the American Society for Histocompatibility and Immunogenetics (ASHI) being held in San Antonio, Texas from October 16-20, 2023.

The latest advances across CareDx’s portfolio of HLA typing solutions and AlloSeq HCT for use in hematopoietic stem cell monitoring1 are being showcased across nineteen abstracts and two company-sponsored symposia. These peer-reviewed abstracts demonstrate the scientific validation and utility of CareDx products and solutions.

“CareDx is proud to be a leading sponsor of this year’s ASHI meeting and driving continued innovation in transplantation with our best-in-class portfolio of HLA typing and workflow solutions,” said Reg Seeto, CEO and President of CareDx. “We are also excited to share the latest update on AlloSeq HCT, a transformative solution for chimerism monitoring in patients undergoing hematopoietic stem cell transplantation.”1

For HLA laboratories, CareDx offers NGS-based typing solutions with AlloSeq Tx,1 QTYPE,1 SSP, and mTilda LIMS (Laboratory Information Management System). AlloSeq Tx171 delivers a novel method for matching transplant recipients and potential donors. The hybrid capture approach to matching is unique to CareDx and gives labs flexibility in gene content and increased robustness over other methodologies. mTilda LIMS software, virtual crossmatch, and epitope analysis are designed to improve transplant outcomes. For allogeneic hematopoietic stem cell transplant (allo-HCT) monitoring, AlloSeq HCT1 offers a streamlined and sensitive approach for NGS-based engraftment monitoring and surveillance following allo-HCT.

CareDx will host two symposia focused on “Innovation Across the Pre- and Post-Transplant Journey”:
