Prospera offers more precise post-transplant rejection assessment
With a 95% negative predictive value, Prospera misses ~3x fewer rejections than serum creatinine.1 Prospera’s proprietary donor-derived cell-free DNA (dd-cfDNA) technology offers early warning signs of transplant rejection and reduces the likelihood of renal allograft failure with a non-invasive single blood draw.1,2
Why now?
Organ rejection is a problem
Many kidney transplant failures occur within the first five to ten years7,8 because organ rejection isn’t caught early enough or treated effectively. As a result, the patient needs a new organ and must start the waitlist process again.
