First Oral Presentation of OKRA Study Data Highlights CareDx Leadership in Multimodality KidneyCare

Symposium Highlights Power of CareDx Artificial Intelligence Solutions

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- 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 2022 American Transplant Congress (ATC) with over 50 oral and scientific poster presentations. CareDx will also be sponsoring a symposium, three product theatres, and an Innovation Day session covering the latest innovations in transplantation.¹ The ATC meeting takes place June 4-8 in Boston, Massachusetts.

“At CareDx our organizational priority is to the transplant patient and community. This dedicated, 100 percent commitment to transplantation is reflected in the record-breaking number of abstracts presented at ATC this year. I am particularly proud of our first oral presentation of OKRA study results, with data from over 50 centers, highlighting the value of our multimodality KidneyCare solution, including AlloSure, AlloMap, and AI-based tools,” said Reg Seeto, CEO and President of CareDx.
