Prospera

For kidney transplant assessment

 

Covered by Medicare, Prospera is a transplant rejection assessment test that uses a simple blood draw to evaluate the risk of rejection of a transplanted kidney.

Through the use of advanced cell-free DNA technology, Prospera increases a provider’s ability to identify otherwise undetected rejection that might lead to kidney loss. Catching transplant rejection as soon as possible can help providers develop a treatment plan to best protect the donated kidney.

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

Organ rejection is a problem

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.
