CareDx Announces New Precision Kidney Transplant Data and Product Innovations at ASN Kidney Week 2025
CareDx Extends Leadership in Kidney Transplant Molecular Testing with Launch of Unique Tissue-Based Gene Expression Assay – HistoMap Kidney
CareDx, Inc. (NASDAQ:CDNA) – The Transplant Company™ – a leading precision medicine company focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions for transplant patients and caregivers – today announced new data presentations featuring CareDx technologies at American Society of Nephrology (ASN) Kidney Week 2025, underscoring the power of molecular biomarkers to advance transplant care.
The company also announced the launch of HistoMap™ Kidney, a tissue-based molecular test that objectively characterizes rejection type and enhances the clinical utility of biopsy results. By leveraging gene expression profiling, HistoMap Kidney delivers deeper insights into immune activity and rejection phenotypes. This approach complements pathology results with molecular information, providing more comprehensive diagnostic insights.
"The HistoMap Kidney launch marks a significant step in our commitment to end-to-end transplant care, bridging histology with genomics to improve diagnosis and therapy selection for kidney transplant patients," said John Hanna, President and CEO of CareDx. "By delivering a more comprehensive and actionable map of kidney health, we're empowering clinicians to make more precise and timely decisions for their patients."
HistoMap Kidney will be available early 2026 through a clinical study.
The company's commitment to innovation is reflected in the latest data featuring CareDx technologies presented at ASN Kidney Week, where new studies showcase how advanced diagnostics and molecular tools are shaping the future of kidney transplant care.
ASN Featured Presentations

Poster, November 6, 2025, 10:00 AM – 12:00 PM
AlloView in Kidney Transplant Rejection. Swamy V, et al.
In this study, AlloView (now known as AlloSure Plus), an AI-powered rejection risk assessment tool, integrated AlloSure with standard-of-care parameters, and demonstrated performance for predicting antibody-mediated rejection (AMR).
-
Poster, November 7, 2025, 10:00 AM – 12:00 PM
Size Doesn't Matter? Effect of Donor Volume on Donor-Derived Cell-Free DNA in Kidney Transplant Recipients: A Single-Center Perspective. Aloia S, et al.
This study showed that the volume of each donor kidney did not significantly impact AlloSure levels or 1-year graft function across 54 living donor recipients. AlloSure values remained consistent regardless of kidney size, supporting its use as a robust biomarker for allograft injury in both adult and pediatric patients.

Poster, November 8, 2025, 10:00 AM – 12:00 PM
Association of Donor-Derived Cell-Free DNA and Peripheral Blood Mononuclear Cells (PBMC) Gene Expression Profile with Graft Function Early After Kidney Transplant. Haririan A, et al.
Results demonstrated that AlloSure and blood gene expression profiling were not confounded by early graft function status, supporting their use for rejection screening starting at week 1 post-transplant.
