Extensive history and experience with cell-free DNA across industries powers new innovative features including a proprietary technique to estimate both the quantity and the fraction (dd-cfDNA %) of donor derived cell-free DNA in a single blood test.
Introducing Donor Quantity Score (DQS) to the Prospera™ Heart test for a clearer picture of rejection risk
Traditional dd-cfDNA tests
- Detect DNA in the blood from the donor heart and reports this as a fraction of the total cell-free DNA in the blood.
- The fraction of dd-cfDNA may be impacted when the amount of total cell-free DNA is atypically high or low.
DQS is the next evolution of dd-cfDNA results
- DQS is the estimated quantity of cell-free DNA coming from the donated heart.
- Unlike traditional dd-cfDNA tests, DQS is independent of fluctuations in levels of total cell-free DNA in the blood.
Celebrating one year with Prospera™ Heart with DQS
The next evolution of dd-cfDNA rejection monitoring
- Developed by Natera, a leader in cell-free DNA (cfDNA) with a trusted legacy in fetal monitoring, oncology and organ health
- Demonstrated in over 10 million tests1
- Utilizes over 13,000 pan-ethnic SNPs and advanced bioinformatics2
- Only Prospera™ Heart with DQS provides two donor derived cell-free DNA metrics and has been shown to improve accuracy in screening for acute cellular rejection (ACR) and antibody mediated rejection (AMR).3

ISHLT Symposium Presented by Natera
This session highlights the exciting new data in support of noninvasively monitoring for rejection risk post heart transplantation. The addition of a second threshold called Donor Quantity Score (DQS) has been shown to improve the overall performance of the test and reduce false positive rates by 37%8 compared to dd-cfDNA fraction % alone. The session will provide an overview of literature in support of the DQS metric as well as share personal clinical accounts in the form of case studies to highlight its value in supporting clinical decision making.

ISHLT Industry Symposium
Two Thresholds, One Powerful Solution:
Enhancing Overall dd-cfDNA Testing Accuracy in Heart Transplantation Using Fraction and Donor Quantity Score (DQS)
60 minute symposium with Q&A
“There is a need for a sensitive, noninvasive surveillance tool for early detection of transplant injury to reduce frequency of biopsy in heart transplantation.”6
Why Prospera?
The current surveillance landscape has limitations and the management of heart transplant recipients is complex and challenging
25% of heart transplant recipients experience acute rejection in their first year4
Survival rates of heart transplant recipients show little improvement over time5
Though endomyocardial biopsy (EMB) is the gold standard in surveillance for acute rejection, it has recognized challenges
Precision optimized for enhanced performance
Reduce the number of surveillance biopsies by using Prospera as your first-line surveillance test
Patients first, partners always
