Introducing ADMIRAL: An Independent Multicenter Analysis

Assessing Dd-cfDNA Monitoring Insights of Renal Allografts with Longitudinal Surveillance (ADMIRAL).
The largest prospective cohort of kidney transplant recipients followed for three years with over 200 biopsy-paired dd-cfDNA results.5

Participating ADMIRAL Study Centers

  • Intermountain
  • Tampa General
  • University of Colorado
  • University of Maryland
  • University of Texas Health Science
  • Virginia Commonwealth University
  • Washington University (St. Louis, MO)

62% Improvement Over Serum Creatinine in Identifying Subclinical and Clinical Rejection

AlloSure is Superior to Serum Creatinine in Detecting Biopsy-Confirmed Rejection from No Rejection*

AlloSure Detects both TCMR and ABMR

AlloSure differentiates the absence of rejection* from TCMR and ABMR.5

Unleash the Power to Predict Early Graft Injury* and dnDSA Detection

AlloSure scores rose a median of 91 days before detection of dnDSA.5

AlloSure elevations (≥0.5%) were associated with a nearly 3-fold elevation in the detection of future dn-DSA.5

*Injury defined in ADMIRAL as: Out of range tacrolimus, BK viremia, dnDSA positive, urinary tract infection, proteinuria, allograft rejection, and recurrent FSGS.

Higher AlloSure Scores Correlated with eGFR Decline

Persistently elevated AlloSure (> 1 result, >= 0.5%) has a nearly 2-fold increase in risk of >25% decline in patients’ eGFR over 3 years.5 No statistical significance within first year.

The Power of AlloSure Kidney to Predict Graft Injury, Actionable Rejection, and dnDSA Detection

Risk of clinical and subclinical rejection increases with higher AlloSure score.5-7

AlloSure is the ONLY dd-cfDNA with Validated Longitudinal Management Using Relative Change Value

Relative Change Value

In addition to the absolute value, the delta/RCV between results can be indicative of allograft injury:

  • Increases in AlloSure results over 61% exceed biological variation8
  • A median increase of 149% between serial results is indicative of graft injury (p=0.02)9

AlloSure is a Surveillance Service Superior to Serum Creatinine

What is AlloSure?

A Surveillance Solution

The first analytically and clinically validated donor derived cell-free DNA (dd-cfDNA) test developed for transplant patients with a targeted SNP assay across all somatic chromosomes.

The ONLY dd-cfDNA service clinically validated for surveillance.

An Early Marker of Injury and Rejection for Kidney Transplant Patients

Broad utility in:

  • Stable patients
  • High risk patients
  • Patients with allograft rejection
  • Repeat kidney transplant patients
  • Pediatric patients

Fast turnaround time of results:

  • Under three days from blood draw

Your Dedicated Partner in Transplant Care

AlloSure isn’t just a test. CareDx supports our providers and patients by providing dedicated Patient Care Managers to facilitate appointment scheduling and blood draw logistics at no additional cost.*


  • Patient Care Managers – Our Patient Care Managers include nurses and former transplant coordinators who understand the complexity in managing kidney transplant patients.
  • RemoTraC®CareDx provides mobile phlebotomy services to patients at no additional cost* to make it easy to stay on track with routine transplant labs and AlloSure testing. Over 9k patients actively use RemoTrac.
  • AlloCare®We developed a free mobile application to support kidney transplant patients: AlloCare makes managing medications and tracking blood pressure, blood sugar, fluids, and weight easier than ever.

*CareDx provides specimen collection through mobile phlebotomists as part of its laboratory service so patients should not have additional out of pocket expenses beyond any coinsurance/deductibles required by their health plans for the test.
